Temperature rising...!

During the past 5 days... it was not like winter, and that too at the end of January.

Take a look at the temperature chart of past 5 days... it's rising above 31°C.
Month Hi: 31.8°C (25/1/08)
Month Lo: 19.0°C (20/1/08)

Even the humidity is also on the higher side.

Weather art



Weather is all around us all the time. It can affect our mood and how things around us look. Think how different the view from your window can look on a sunny summer's day and on a cloudy wet winter's day.

Make your own weather symbols

Many of you will have seen weather symbols on TV weather forecasts. Try designing some of your own.

Draw a picture

Paint or draw a picture of your school, garden or other interesting view. Colour the picture in to show the scene in different types of weather. Think about how different colours can be used, bright yellow and oranges for sunny, dark greys for cloudy and blue for wet. Also think about how this makes you feel. Does the sun make you happy, do cloud and rain make you sad? This can create an atmosphere to your painting, and change how people feel when they look at your art.

Weather colouring

Below are some weather pictures for you to print out and colour in. Ask an adult to help you to print it out. You can then colour in your picture.

Arboviral Encephalitides

Arboviral encephalitides are mosquito-transmitted viral diseases capable of causing encephalitis (brain inflammation). Varieties found in the United States include eastern equine encephalitis, western equine encephalitis, St. Louis encephalitis and La Crosse (LAC) encephalitis, and West Nile Virus encephalitis. Encephalitis is a very serious disease that can lead to coma, brain damage and death. Eastern equine encephalitis is particularly deadly, with a 30-35% fatality rate, according to the U.S. Centers for Disease Control and Prevention. However, cases are rare -- an average of four a year in the U.S., according to the CDC.

Most viral encephalitis infections either don't produce any symptoms at all or only lead to general flu-like symptoms such as fever, headache, muscle ache and malaise. Symptoms of severe encephalitis include high fever, stiff neck or back, sensitivity to light, vomiting and confusion.

West Nile Virus

What Is West Nile Virus?
West Nile virus (WNV) is a potentially serious illness. Experts believe WNV is established as a seasonal epidemic in North America that flares up in the summer and continues into the fall. This fact sheet contains important information that can help you recognize and prevent West Nile virus.

What Can I Do to Prevent WNV?
The easiest and best way to avoid WNV is to prevent mosquito bites.

When you are outdoors, use insect repellent containing an EPA-registered active ingredient. Follow the directions on the package.

Many mosquitoes are most active at dusk and dawn. Be sure to use insect repellent and wear long sleeves and pants at these times or consider staying indoors during these hours.

Make sure you have good screens on your windows and doors to keep mosquitoes out.

Get rid of mosquito breeding sites by emptying standing water from flower pots, buckets and barrels. Change the water in pet dishes and replace the water in bird baths weekly. Drill holes in tire swings so water drains out. Keep children's wading pools empty and on their sides when they aren't being used.
What Are the Symptoms of WNV?

Serious Symptoms in a Few People. About one in 150 people infected with WNV will develop severe illness. The severe symptoms can include high fever, headache, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, vision loss, numbness and paralysis. These symptoms may last several weeks, and neurological effects may be permanent.
Milder Symptoms in Some People. Up to 20 percent of the people who become infected have symptoms such as fever, headache, and body aches, nausea, vomiting, and sometimes swollen lymph glands or a skin rash on the chest, stomach and back. Symptoms can last for as short as a few days, though even healthy people have become sick for several weeks.
No Symptoms in Most People. Approximately 80 percent of people (about 4 out of 5) who are infected with WNV will not show any symptoms at all.
How Does West Nile Virus Spread?

Infected Mosquitoes. Most often, WNV is spread by the bite of an infected mosquito. Mosquitoes become infected when they feed on infected birds. Infected mosquitoes can then spread WNV to humans and other animals when they bite.

Transfusions, Transplants, and Mother-to-Child. In a very small number of cases, WNV also has been spread through blood transfusions, organ transplants, breastfeeding and even during pregnancy from mother to baby.

Not through touching. WNV is not spread through casual contact such as touching or kissing a person with the virus.
How Soon Do Infected People Get Sick?
People typically develop symptoms between 3 and 14 days after they are bitten by the infected mosquito.

How Is WNV Infection Treated?
There is no specific treatment for WNV infection. In cases with milder symptoms, people experience symptoms such as fever and aches that pass on their own, although even healthy people have become sick for several weeks. In more severe cases, people usually need to go to the hospital where they can receive supportive treatment including intravenous fluids, help with breathing and nursing care.

What Should I Do if I Think I Have WNV?
Milder WNV illness improves on its own, and people do not necessarily need to seek medical attention for this infection though they may choose to do so. If you develop symptoms of severe WNV illness, such as unusually severe headaches or confusion, seek medical attention immediately. Severe WNV illness usually requires hospitalization. Pregnant women and nursing mothers are encouraged to talk to their doctor if they develop symptoms that could be WNV.

Heavy snow in China

This week has seen a blast of winter arrive across China, bringing freezing temperatures and heavy snow falls. An unusually large swathe of the country has been affected by the cold weather. Over the last two days especially, heavy snow has brought chaos across the southern provinces of Hubei, Hunan and Jiangxi.

For Hubei, the first snowflakes began to fall over a week ago, with it now experiencing its heaviest snowfall in 16years. Plummeting temperatures have frozen pipes cutting off the water supply to many residents so that fire engines had to be used to carry in fresh supplies.

In Hunan too it is their heaviest snowfall in more than 5 years and has resulted in treacherous conditions across many of the province’s roads. Some 120,000 cars are said to have become stranded in Hunan for days, with almost half a million passengers having to wait until Thursday to be rescued. The government has resorted to using several hundred tons of industrial salt in order to keep the roads open. Air travel was also affected with the freezing temperatures delaying or cancelling flights.

There were also similar problems in the province of Jiangxi as thousands of cars became stranded when a bridge across China’s Yangtze River had to be closed.

The capital did not escape either with snow blanketing Beijing on Thursday. The National Meteorological Centre of China is forecasting the winter blast to continue over the next few days, with further snow falls expected to affect many parts.
