Small Fluctuations In Solar Activity, Large Influence On Climate

11 connection between the mercy of the sun in the stratosphere of the tropical Pacific Ocean was running the weather to create a model of synchronization. The phase of the world this week, and Science magazine appear 』prolific. This study helps to get the edge in the predictive behavior of the most serious scientists. Several air-conditioned, India, like the monsoon and tropical Pacific prior fiscal year.

Scientists Center for Atmospheric Research (NCAR) and the weather by a powerful computer model of one of three international teams was more than one century. In meteorology, the battle more difficult question 1: If you are about to drive such a small format change the key of how the solar energy from the sun the whole world depends on 11 only 0.1 percent a year. Weather patterns on earth?

What two in the two regions, the effects of the sun is nothing new. Seems irrelevant. Response at maximum light, the substance of the Pacific sea surface temperature and stratospheric chemistry. Sunday, some air movement is a way to amplify the effects of the sun. This can be in the clouds cover the entire area and sea surface temperature changes in the very wind and rain. For best results the whole world and some hot and subtropical climate.

“Sun is in North America, such as the winter rain, and sea connections to work as the stratosphere,” NCAR scientists Gerald Meehl said the lead author. As to increase the players understanding of the solar cycle “can provide insight into the role. Science in weather patterns are expected to match the next 10 years.

This research is the National Science Foundation, NCAR is sponsored and supported by the State Department. Meehl global events like the recent construction of several documents and co-workers, some of Ranina between the peak of solar activity, however, and they explore the different links. Changes in surface pressure under El Nino and La Nina pattern of large width, known as the associated vibration.

And cooling water in the equatorial Pacific Ocean is the connection between the peak of solar energy, the first of NCAR, who co-Vanharimarifana Kororadorisachiasoshieitsu emergency was discovered by the author of the new paper.

Below the top.

Meehl vibration of the sun to generate changes in how his body is supported by his colleagues to establish a mechanism for one or two. You can work to expand the response of the tropical Pacific climate in the world together.

The first team is absorbed by ozone, the theory is a high-end products to see more sunspots solar energy. Stratosphere. Ozone stimulates the production of energy at the same time, the stratosphere, which absorbs more solar energy is most intense sun warms the air above the tropics. The most prominent non-uniform heat from warming the stratosphere, occur in low-latitude stratospheric wind. The editing is interconnected through a chain of processes, back up the healthy end of the summer rains.

At the same time, the date of solar maximum, a little heated. Surface of the tropical Pacific Ocean. Sunscreen, the clouds are not normal. Lead to the generation of increased evaporation of water vapor and heat some more. Rattouesuto tropical Pacific Ocean in the field of water, usually carried out in the rain to replenish and strengthen the mechanism of stratospheric open rain.

The top-down, with the strengthening influence of the stratosphere, the work of the rats, under the influence of the ocean. Balance very bright drier areas, other major enhancements in each sub-tropical low clouds to allow more sunlight to these changes. To encourage the air to generate a response of the skin and a good feedback loop.

These maximum response. Stratosphere. Sea, between the eastern equatorial Pacific cold in the sun, and also drier than normal conditions to produce a similar Ibentoraninya. But focus on the east about 1-2 more than usual cool Fahrenheit, is only about half of a strong La Nina. Showed a correlation with changes in wind patterns. Stratosphere.

Sun around the world for one year, or up to two single sunspot activity. Ranina like model is called slow change is likely to form as El Nino and solar maximum – the water instead of warm and cool tropical eastern Pacific. The answer is only about half of the strong flow of water moving here. As the warm El Nino and La Nina is a delay, as there is no consistent pattern occurs during solar cycle peak.

Building a cold sea.

Solar maximum, or real increase Ibentoraninya, the actual event, the delay of El Nino. 1989 ~ 1988 La Nina occurred near the peak year of solar maximum. Associated with significant changes in weather patterns such as unusual or strong La Nina. Air dry winter in the southwestern United States and usually mild.

Most of the regional weather patterns and sea surface temperature and precipitation in the Pacific storm in India. Driven by increased air, the world’s tropical and subtropical. Therefore, new studies are helping scientists to reduce the predicted solar cycle. To evaluate the flow and weather patterns associated with it in the region. In May, the next 10 years, or two or more different.

The answer is three views.

Elusive mechanism, in order to draw a connection to the sun and earth education team. Three one computer model is required to view the overlapping of the weather.

One is to analyze the relationship between sea surface temperature and the lower atmosphere. Cold War produced a small equatorial Pacific region during the solar maximum. Second generation model is the mechanism of ozone. Stratosphere. , However, the increase in meat production in some large tropical rain smaller format. Practice.

Version 3 of the ocean – atmosphere interaction is ozone. First time the combination of the two is found to generate a response of the tropical Pacific Ocean. Observed near the truth during the solar maximum.

“With the help of increased computer power, improved version was found in observational data. We have to clarify the details of the connection mechanism, climate change, the sun. And our air” Meehl said Ta.

Poor monsoon lowered hydro electricity generation in HP

Scanty rains have resulted in low hydro electricity generation in Himachal Pradesh this year.

Lack of snowfall is being attributed as another big reason that affected the flow of rivers and streams in the region and resulted in lower power generation.

86 megawatt Malana Hydro Electric Project is one the hydel projects which has been affected.

According to the General Manager of the Hydro electric project, J.K.Beri, Compared to 2008, the production level of electricity has decreased by 5,49,68,808 units.

"Last year from April 2008 to August 25, 2008, we generated 24,71,97,856 units of electricity. This year in the same period, we have managed to generate just 19,22,38,048 units of electricity. The reason is less rainfall and low temperature during the melting time of glaciers," Beri said.

The peak season to generate power starts from June and ends in September.

Beri added that as the peak season is over, they might not be able to fulfil the generation loss.

"I think we may not be able to recoup our generation loss this year as we don't expect enough rainfall in future," he said.

Himachal Pradesh plays a significant role in the supply of electricity to northern grid.

The state supplies electricity to Punjab, Haryana, Delhi, Uttarakhand, Rajasthan and Uttar Pradesh.

Himachal Pradesh records over 50 percent deficit rainfall

Himachal Pradesh has received 53 deficit rainfall this year and there is not much hope of overcoming this shortfall as the monsoon in the state generally starts receding from Sep 15, weather officials said Sunday.

“The overall monsoon situation in the hill state is still precarious. Almost the entire state has received less than the normal average rainfall,” meteorological office director Manmohan Singh told IANS.

“The deficiency in the cumulative rainfall from June 1 to Aug 30 is still 53 percent. This means, the state saw just 292 mm average rainfall against the normal average of 625 mm.

“As the southwestern monsoon in the northern areas of the country starts receding from Sep 15, it’s now difficult to fill the gap (deficiency in rainfall).

“In August, the state generally receives 108 mm average rainfall. But this time only 44.5 mm rainfall was recorded this month,” the weather official said.

State Agriculture Director J.C. Rana said this was the lowest monsoon rainfall Himachal Pradesh has seen in the past few years.

“Of course, it’s (low rainfall) alarming as more than 80 percent of the horticulture and agricultural activities are rain-fed,” he said.

The deficient rainfall has triggered drought-like conditions across the state.

“The deficit monsoon rains have damaged both the kharif crop now and the rabi crop in winter, when the rains were more than 50 percent below normal. This is the third successive crop failure,” Rana said.

The meteorological office here said that except Una all the 12 districts have received less rains so far.

While there was 85 percent deficit rainfall in Chamba, the figure in Lahaul and Spiti is (72 percent), Sirmaur (63 percent) and Shimla (57 percent).

An initial survey by the agriculture department says cash crop production fell more than 50 percent in several districts, and in some cases, by as much as 80 percent.

Chief Secretary Asha Swaroop pegged the total loss for agriculture and horticulture at Rs.850 crore (Rs.8.5 billion) and Rs.250 crore respectively.

“The government has doled out Rs.35 crore as relief to farmers and agriculture-dependent sectors,” she added.

The government has declared the entire state drought-hit.

India's monsoon may be the worst since 1972

India's poor monsoon rains will improve slightly in their final month but will still end the June-September season about 20 percent below normal, a top official said, making this year's rainfall the worst since 1972.

Weak and uneven monsoon rains have ravaged India's rice crop and hit the sugarcane, soybean and groundnut crops as well as disrupting the flow of water into the main reservoirs, which are vital for hydropower generation and winter irrigation.

"We expect at least 4-5 percent improvement in the seasonal rainfall deficit for the entire season from the current level," Ajit Tyagi, director general of the India Meteorological Department, told Reuters on Friday.

India last suffered a monsoon failure in 2002, when rainfall was 19.2 percent below average through the season, and July rains were 54.2 percent below normal. India's crop output in 2002/03 fell 18 percent.

This year, June rainfall was the worst in over 80 years, while July saw a 5 percent deficit. August began with an exceptionally dry two weeks, followed by near-normal rains in the later part of the month.

From the start of June to Aug. 26, rains were 25 percent below normal, data showed on Thursday.

"In 2002, the seasonal rainfall deficit was 19 percent. The only difference is that this year's July rainfall was relatively better than 2002," Tyagi said.
