Ring solar ECLIPSE (Annular) is predicted to be across most of the surface of the earth today (21 May 2012) local time in the eastern hemisphere with a magnitude of 0.9439. Called the eclipse ring because the disk of the sun not covered the disc of the moon looks beautiful like a glowing ring.

Honey, a rare sight could not be seen in the region of Indonesia because when an eclipse occurs, the sun had not yet risen in most regions of Indonesia. This eclipse can be seen in eastern China, southern Japan, as well as the western part of the United States and Canada. Guangzhou, Tokyo and Albuquerque will be on the central path. The peak of the eclipse will occur in the north Pacific, south of Aleutian Islands, with a duration of 5 minutes 46.3 seconds, and will end up in the western part of the United States.

The events of the eclipse always attract attention among scientists. Through technological devices, they are trying to reveal the mystery of the eclipse, including the search for scientific answers about the relationship of astronomical phenomena with the temper of the weather in the face of the earth.

A group of meteorological find the fact that at the time of the eclipse of the sun, the temperature on the earth's surface has decreased by about 5 degrees Fahrenheit or 3 degrees Celsius. But they do not yet know whether there is a change of speed and direction of wind associated with eclipse events.This theory comes from 1901, when H. Helm Clayton saw a change in direction of wind due to a solar eclipse, the said Giles Harrison, a physicist from the University of Reading in England, was quoted as saying Oktomagazine from National Geographic.

Through his paper H. Helm Clayton explained that these changes could be caused by the hurricanes. Clayton refer to it as the eclipse cyclone or hurricane of the eclipse. Harrison explained that the hurricanes only occur in the area around the dark due to the shadow of the moon.

Harisson invite Suzanne Gray, the scientists the field the atmosphere of the University of Reading, to collect samples of data taken from one of the events of a solar eclipse in August 1999 in almost the entire European continent. Both of them investigate the difference condition before and after the occurrence of a solar eclipse based on the data recorded a number of stations agency meteologi English about the change of direction and speed of the wind from places that are more sunny.

Both use the conditions of the pre-eclipse and computer modeling to create a forecast (for the day) when there is not the shadow of the moon, then compare the result with the data that they acquired during and after the eclipse of the sun occurs.

From the results of the comparison, it seems the significant changes of the wind. Both noted the absence of reduction in wind speed of 1.6 mph (2.5 km/h). The wind is also changing. The Data shows that the wind is blowing as far as 20 degrees more toward the north during and after the eclipse of the sun.

Global Climate

Scientifically, a solar eclipse occurs when the moon passes between the earth and the sun. That is why most of the earth's surface into the dark. The eclipse of the sun the annual occur when the diameter of the angle of the moon smaller than the sun, causing the sun to look like an annular (ring), blocking most of the light of the sun. The full eclipse will only be visible in a number of areas with a distance of thousands of kilometers.

Although physically smaller moon, but the shadow is able to block out the light of the sun in full because of the month which is the average distance 384.400 kilometers from earth closer than the sun which has an average distance 149.680.000 kilometers.In Indonesia, observations of the influence of the eclipse of the sun to changes in the parameters of the weather such as air temperature, air humidity, wind speed and air pressure ever do in Gunung Sugih, Lampung on 26 January 2009. Observations were made before, during and after the events of the eclipse of the sun using observation stations automatic weather (AWS) periodically with an interval of observation of one hour and 10 seconds-an.

The Data obtained, air pressure and air humidity is increased during the occurrence of the eclipse. But from some of the weather factors were observed, only the air temperature and air pressure has a relationship with the eclipse of the sun. A decrease in temperature by 4-5C occurred during the events of the eclipse and reached a point a minimum of 5 minutes after the occurrence of the eclipse.

A solar eclipse also affects global climate change. A number of researchers find the relationship between the movement of the sun and the events of La Nina and El Nino in the tropical region of the Pacific Ocean. The study has been broadcast by the US National Center for Atmospheric Research (NCAR) pada16 July 2009. When the sunlight reaches its peak have impact reaching far and often smooth for the deposition of the tropics and of system the weather in most regions in the world, says Gerald Meehl, a scientist at NCAR was quoted as saying

The study describes, when the sun reaches the activity maximum, it is warming in many parts of the smoke cloud in the Pacific Ocean. This condition is able to increase evaporation, increasing rainfall and cool the eastern tropical Pacific. The result was similar to the events of La Nina, although the cooling is centralized in the area which is to the east and is only half as strong for events typical of La Nina.

It is undeniable that the events of La Nina and El Nino are associated with changes in the temperature of surface water in the eastern Pacific. All of that can affect weather patterns around the world.
