The study at the Northern Hemisphere Circulation department has found that the present climate change has a computer representation of the whole atmosphere, and the ocean along with the land surface they are underestimating the changes in the air pressure, which will lead to the global weather patterns.
While we see what they reveal the air pressure has dropped about 4 millibars
over the continent of Iceland in the last 50 years and has risen by up to 3 millibars in the sub tropical areas, the climate trends are less than 1 millibar.
Research is able to show that in the last thirty years the air pressure has contributed to about 1°C to warming over the United Kingdom in wintertime and that adds up to 3°C in the Siberian continent, as well as 60% of the country's rainfall will increase as seen over Scotland. Over the South of England, the air pressure has likely made winters much milder but more windier.
The climate is good at simulating the temperature changes, but the simulations of pressure trends in the northern hemisphere is not a realistic one. If we could understand these predictions the climate change would be improved.
Winter made a mess in the United States from December 2000 all the through till February 2001 and as the temperatures averaged below the normal which was the first time since winter 1993-94 and this was a year after the U.S. had its warmest winter on record.
A lot of the cities in the Midwest and the Northeast have set a snowfall record and around the globe there is heavy rain soaking Western Europe with a record of cold weather in Eastern Europe.
We are gradually learning more about the atmospheric waves that circle the planet of the tropics and the sub tropics this will help improve the forecasts of the hurricanes, winter floods, rain, even El Nino.
Meteorologists have found that the hurricanes are four times more likely to happen in the Gulf of Mexico and the western Caribbean Sea where the of the part of the wave that brings the cloud and rain is over that area, and than during the opposite phase, it will bring the clear skies.
The atmospheric waves are like huge, slow-moving ocean waves that will rise up in the Indian Ocean and then they travel really slowly across the Pacific ocean until they reach the coast of the Americas where they start the thunderstorms.
One phase of the waves will pass over an area, and then the air slowly sinks toward the planet and the winds that are near the surface are from the east. Air will slowly rise and the winds will blow more from the west in the lower atmosphere. During a westerly wind phase, the hurricanes more likely, create the waves in a counterclockwise swirl in the air north of the equator.
