"98A" and "97A" - vanished!!
"98A" and "97A" - vanished or vanishing.
Latest satellite image shows that both the systems have almost vanished..!!
Chennai:
Today morning Chennai was lot colder than previous 15 days.
Low was 22.9°C (6:24am).
Now (3:26pm) temperature is reducing fast.
Very low humidity 49%, that means a DRY & cold night ahead.

Rainy days and your child!!
Taken from http://mymadrascurry.blogspot.com
My son doesn’t take well to rainy days. Most children below the age of five, find the monsoon season extremely boring. Parents pose restrictions on kicking in puddles and getting wet. However, playing indoors need not boil down to watching TV.
Here are a few games to play with your child and his/her friends when the rain plays spoil sport.
1. Puppet show - Take a big cardboard box and make a dupatta curtain in the centre. Open out the flaps in order to put puppets through the back and use front flaps as windows. The child’s dolls, toys like cars, spoons, etc. can be used and a story can be spun with imagination.
2. Hide the loot – Give your child ten items and tell them to hide one item in a bag. Guess the item hidden by asking your child to describe what he/she hid.
3. Photo fun – Make a photo collage of your child’s favorite pictures from your recent vacation on a chart paper and add comment stickers or emoticons in appropriate places. Hang in your child’s room when complete. Photo collages make great décor ideas too!!
4. Colour splash – Paint a picture using old toothbrushes, bottle caps, sponge, waste wool, fingers, hands, toes and just about anything other than paint brushes. Make sure you do this on the floor and don’t get any paint onto a costly outfit or a carpet.
5. Junk art – Use material from all over the house. Cotton, old magazine pictures, buttons, sand, old shoe lace, wrapping paper and just about anything. Make a Christmas scene or a meadow and watch your child’s imagination flitter like a butterfly!!
6. Dress up – Give the age old game of robber and police a twist by dressing up yourself and your son to fit the roles. Dressing up like a character in a story is a good way of getting the child to understand the story completely. The parent can be the narrator and the child can play the central character.
7. Shadow play – For those of you who are not scared of the dark and have brave children, its time to light a candle and put on the musical night lights. Spin a story with shadow figures. The crow looking for water to drink is a beautiful tale to spin around one’s fingers.
8. Cook with mommy – This is a game that can be messy. Children love helping their grown-ups in their grown-up things. Explain that cutting and cooking on the stove/oven are grown up things to do. However the child can help wash the vegetables, add certain ingredients, beat an egg and a whole load of other things that can be fun.
9. Song and dance – Teach your child simple dance steps to his/her favorite song/rhyme. Dress him/her up like a pop/rock star and have your own Indian Idol show at home!!
10. Puzzle when it drizzles – Buy a puzzle for your child and hide it from them till the monsoon arrives. On a dull, dreary “can’t do anything else” day give them this surprise gift and watch them lose track of time.
Here’s wishing all you mom’s a happy fun filled Monsoon!!

Winter woes
"Winter woes" from http://mymadrascurry.blogspot.com
Winter means many things – the season of Christmas, hot chocolate, warm woollies, snowmen and dry skin. If winter mostly defines the last one for you, here are a few tips that could change your skin making it as soft as snow.
1. Winter dryness is found in people of all ages. The common sites for dryness are upper arms, thighs and lower legs but face, neck and hands also show signs of dryness. Knowing your skin type is the first thing to do before one starts a skin care regimen.
2. The 3 major skin types are – dry, oily and combination skin. It is rare to find anyone with a normal skin type. Different parts of the body could come under these categories. For ex: It’s normal to have an oily nose, normal skin type on cheeks and very dry hands.
3. A daily skin care routine should be as follows – Cleansing, toning and moisturizing. Using a product appropriate to your skin type is important. Some natural products can be used to combat dry skin effectively. Yogurt can be used as a skin cleanser, acting as a natural moisturizer. In order to remove dead cells a mild scrub like oatmeal can be used as it heals and soothes dry skin. Honey when applied to the skin, is healing and moisturizing.
4. Moisturizing often is important as itching is the main problem faced by people during winter. If hands and feet are prone to dryness it’s a good idea to invest in moisture rich hand cream or a foot cream. Moisturizing after a bath or after washing is very important, as the skin dries when water evaporates from the surface leaving it drier than it was.
5. Most of us find smiling difficult during the winter as chapped lips cause a lot of pain. Using a lip balm or beeswax is a good idea.
6. The most important thing to do during the winter months is to drink plenty of water. Feeling thirsty is not an indication of the body’s requirements of water. Drinking at least 2 litres a day helps combat most winter woes.
7. Eating lots of fruits and vegetables rich in Vitamin A helps repair damaged skin.
8. Some home remedies can also be used for removing winter dryness. Mix one teaspoon of honey with a teaspoon of milk. Apply this mixture on skin for 15 minutes and wash it away with warm water. Mix equal parts of olive, mustard and sesame oil and use it as a body massage.
9. A good winter face pack can be made straight out of your kitchen. Combine an egg yolk with a tablespoon of yogurt and a tablespoon of honey. Add a 1/2 tsp. of almond oil. Apply to and let it dry. Wash off gently with warm water.
10. Remember that some of the simple daily routines can also remove moisture from the skin. For example, bathing with a harsh soap, long steamy showers may give you relaxation for your sore muscles, but hot water eliminates your skin’s natural oils more quickly. So, altering these daily routines with dry skin care instructions can definitely retain the skin’s moisture.
11. Dandruff is another common embarrassment of winter. There are 2 kinds of dandruff: The Dry Scalp Type: The scales are fine, thin, white or grayish and dry. The hair is dry and often lacks lustre. Itching maybe mild to moderate. This is the more common type of dandruff and is more prevalent during winters.
The Oily Scalp Type: The scalp is generally oily. And this malady may occur in well defined and confined patches or diffusely all over the scalp. Later the condition may extend to the eye brows, eye lids, beard, external region, groins, etc. Patients suffering from oily dandruff gradually develop thinning and later loss of hair.
Whatever kind it be it should be treated as soon as one spots the symptoms.
Being more vigilant in caring for and nurturing your skin in the winter months helps pay off for skin that's summer-ready when the seasons change. Enjoy the glow of good skin this winter!!

Potential "97A" and "98A"
Can you believe that 2 tropical disturbance in Arabian sea and that too in December??
"97A"
-------
This system is there in south-western Arabian sea for almost 2 weeks now. It's actually a remnant of "07B". This system is almost died out.
This prolonged system has given rise to another disturbance.
"98A"
-------
Now this "98A" is very close to Kerala.
Going by latest satellite image...
We can see a core and some circulation around it.
And latest TPW also suggests more moisture in that Area.
We should wait for another 24 hrs to see if any threatening formations are there.
There's no predicted movement yet, Might move in a west-north-west direction and dissipate before reaching any LAND.
Chennai:
Today morning it's cloudy and mild.
If "98A" becomes into a tropical depression then North-east monsoon might trigger again for us and get some showers.

Incessant late monsoon rains in Chennai
18-December-2007 - Revisited
Taken from http://somasundaram.info
Starting on late Monday night it has been raining non-stop in Chennai and surroundings. A low-pressure system that has developed in the Bay of Bengal is moving slowly through Tamil Nadu. This stalled system has produced close to 8 inches of rain in various part of Tamil nadu. In the city normal life has been disrupted. The rain at times heavy has made traffic of cars, trains, and buses very difficult.
Our plans in Chennai are also affected. We couldn’t do most of the outside activities. However, the plight of even less fortunate is bad. Many of them have to live in cold and wet places with no recourse to dry living conditions. Schools have been canceled. Businesses are also affected as most stay home to avoid the problem of navigating flooded streets and highways.
The fishermen have been advised not to go into the seas so as to avoid high winds and rough seas.
*********************************
Today (18-Dec-08). It was a DRY and CLEAR day.

What Exactly Is The Dew Point?
The dew point is a temperature at which the air becomes saturated. But as most weather definitions go, this is too simple of a definition.
Prepare yourself, what we are about to delve into actually takes some thinking. Why? Because the concept of moisture in our atmosphere, how we measure it, and how it changes, is pretty complex. Sorry about that.
However, you just may learn something that will be on Jeopardy, so let's dig in.
(This is a sling psychrometer (sigh-crom-a-ter) which is used to measure important atmospheric data, which then can be used to calculate the dew point)
First of all, it is important to realize that the dew point temperature is just that, a temperature. But the air temperature and dew point temperature are two very different things. The dew point temperature is the point at which the air must be cooled in order for the the air mass to become saturated (assuming there is no drastic change in pressure or moisture content).
So, when the air temperature and dew point are equal, does that mean it rains or snows? Not necessarily, because the process of forming rain is more complex. Also, keep in mind that rain falls from above. So, while the surface air may be saturated, that doesn't mean the air above you is saturated. In fact, before rain develops, there needs to be a cloud, and the process of cloud formation depends upon more than just saturated air. Such factors could be the type and size of aerosols which water vapor can condense upon. These aerosols are called cloud condensation nuclei (CCN). You see, it is not as simple as saying "if you have saturation, then you have a cloud or rain drop." However, it is the first step, and that's why dew point and saturation play a close role in forecasting rain.
The dew point is used a lot by TV meteorologists and seen on most current weather conditions because it's a great indicator of the moisture content of the air, or humidity. The higher the dew point temperature, the higher the humidity. Okay, this is where some thinking comes in, because the relative humidity and dew point both describe the moisture content of the air, yet they are different at the same time.
About Relative Humidity:
One thing you'll notice is that when the air temperature is close to the dew point, the relative humidity is high (often 80% or greater). But the relative humidity is "relative"or dependent. Relative humidity is dependent upon the temperature. So, if the temperature changes, the relative humidity will change. Dew point is a better "absolute" measure of the air's moisture content. Here's a good example of why:
Temperature Dew Point Relative Humidity
90 80 = 67%
100 80 = 47%
110 80 = 33%
From this table above, look at the relative humidity of 33%. Looks like a comfortable relative humidity, right?
Probably not. Sticky, sultry and oppressive are appropriate adjectives for 110 degree heat with an 80 degree dew point But why is the relative humidity so low? Because relative to that hot temperature of 110 degrees, the air is no where near saturation. Remember, we would have to cool the air down to 80 degrees (with no pressure change) in order to saturate that air mass (remember that's the definition of dew point). That's a 30 degree cooling! If our air temperature is 90 degrees, now the air is 67% saturated and we only have to cool the air 10 degrees to reach saturation. What if the air temperature was 80 degrees and the dew point was 80 degrees? The air is saturated, it 100% relative humidity and it is likely that you would be experiencing either rain, snow, mist or fog.
So, relative humidity is just that...relative, meaning it depends. It depends on the temperature of the air. Dew point temperature is a better "absolute" measure of moisture in the air.
In general, I consider dew points above 70 degrees F very uncomfortable. Most people consider dew points near 55 degrees F and higher to be necessary for severe weather. That's just a guideline though.
Why does cooling the air to the dew point cause saturation?
The cooler the air, the less energy it has. It takes energy for molecules to break free of the liquid bonds (or solid in the case of ice). So if you cool the air, you're reducing the energy the molecules need to escape the liquid bonds and become a gas. In turn, this encourages condensation. If you were to heat the air, you're adding energy and encouraging evaporation.
This doesn't quite explain why cooling to the dew point will cause saturation. In order to understand saturation, first understand that water in our atmosphere is constantly evaporating and condensing. H2O molecules are constantly coursing back and forth from a liquid to a gas and vice versa. What is important to the growth or decay of a water droplet is which process is dominant. For example, if you had 10,000 molecules evaporating and 1,000 molecule condensing, then evaporation is dominating and a rain drop or ice crystal is not likely to form. But when you cool the air, you reduce the energy molecules need to evaporate. At some point 5,000 molecules are condensing and 5,000 molecules are evaporating. The temperature at which this occurs, is called the dew point. It's the point at which condensation and evaporation are equal. Or you could consider it the temperature at which condensation has a chance to dominate over evaporation. And the reason that's important is because when condensation dominates over evaporation, it's finally possible to form a rain drop or ice crystal.
I mentioned several times about cooling the "air temperature", I am using the air temperature to approximate the temperature of the water vapor in the air. Although air is made of Nitrogen, Oxygen, water vapor and other stuff, we can make the assumption that the "air temperature" is also the temperature of the water droplet. It's kind of like trying to separate the temperature of the water in tomato soup from the temperature of the entire bowl of tomato soup. For all practical purposes, the temperature of the water is probably the same as the temperature of the entire soup. I mention this because it's not the temperature of the air as much as it is the temperature of the water vapor that is important

Heavy rainfall in Rameswaram region.
For the past 3 days, it's unusually heavy rain over Rameswaram region. Recorded around 40cm in 3 days. Even a cloud burst of 19cm on 15-Dec-08.
Almost there is no such rain forecast thru GFS models and no visible evidence in Satellite images. Purely a local disturbance.
Satellite pic shows...
Still lot's of activity over the South-Arabian sea in the form of stable "97A".
And cloud activity can also be seen over the South-BAY. There's a GFS suggestion of LOW pressure formation over that area and moving in a WEST direction.
Chennai:
Night was mild around 24 degrees and Now (3:45PM) the temperature is gradually reducing. Tonight we might get up to 22 degrees. From tomorrow morning there'll be DEW.

Will there be a final showdown??
Will there be a final showdown of rain in Chennai before the end of this Season..??
As far as the latest GFS models, the answer is "NO".
Latest satellite pic shows some activity near the west of Srilanka.
These cloud formations in southern bay would not move North or North-westwards, unless the Anticyclone seen over Northern bay region moves away.(pls view following image for Anti-cyclone over north bay). That anticyclone is there for the past 15 days.
Latest "Sea Surface Temperature Chart" also shows cooling down near the tamilnadu coast as well as central bay. This phenomenon will drastically reduce the cloud formation over the Bay.
Chennai:
The low cloud formation during mornings have reduced. Today it was almost NIL.
Only good thing is the North-east air current is strong without carrying any moisture. For the past 3 nights, the minimum temperature was not low, this time of year it should be COLD around 21 degrees.
Last: "97A" in Arabian sea (remnant of 07B) is turning BACK, this is a very rare phenomenon. We'll report on it if it gathers strength and moves in a East Direction.

These cloud formations in southern bay would not move North or North-westwards, unless the Anticyclone seen over Northern bay region moves away.(pls view following image for Anti-cyclone over north bay). That anticyclone is there for the past 15 days.
Latest "Sea Surface Temperature Chart" also shows cooling down near the tamilnadu coast as well as central bay. This phenomenon will drastically reduce the cloud formation over the Bay.
Chennai:
The low cloud formation during mornings have reduced. Today it was almost NIL.
Only good thing is the North-east air current is strong without carrying any moisture. For the past 3 nights, the minimum temperature was not low, this time of year it should be COLD around 21 degrees.
Last: "97A" in Arabian sea (remnant of 07B) is turning BACK, this is a very rare phenomenon. We'll report on it if it gathers strength and moves in a East Direction.

Chennai witnessed a classic cricket TEST match
"Well done Team India !!"
Our forecast for the whole of test match stood perfect.
Thanks to weather and Team India, Chennai witnessed yet another classic test match.
Tomorrow we'll post the HIGH LIGHTS package video download in our other site Free Download Shop
For the past two days the minimum temperature was not low, even it's increasing every night. Yesterday (14-Dec-08) night it was 26.2°C (2:14am).
Thru the day it was HOT and mildly humid.
Even the cloud formations seen in mornings for the past 2 days was not seen today.
Today there was very little cloud movements.
Going by the latest satellite pic,
There's still a Anti cyclone over the northern bay.
And we can see lot's of activities around Southern bay region just EAST of Srilanka.
Hats off to "INDIAN CRICKET TEAM"..!
The GFS suggests, that there'll be a MILD low pressure system forming in another 36 hrs and it'll move across Srilanka (again) in another 2 days. No suggestion of moving up and crossing Tamilnadu coast. This system will trace the path of "07B".
Still the remnants of "07B" can be seen over South-central Arabian Sea with some power. This system will enter the COOLER waters near Arabian peninsula and die out.
Only 30% chance of reaching the Yemen or Saudi Arabian coast.
