New weather model: Record temperatures from 2009

he effects of global warming are expected to accelerate as early as 2009. These are the findings of British researchers who have developed a 10-year computer model that takes into account previously ignored natural variables.

Between 2009 and 2014, records of heat should follow one another, eclipsing 1998 considered by meteorologists as the hottest year, reads Science magazine of 10 August. This is what emerges from a new climate model developed by British scientists at the Hadley Center in Exeter.

Unsatisfied with existing computer simulations, English researchers integrated data on natural variations of the oceans and oceans, Atmosphere to their program called DePreSys (Decadal Climate Prediction System). “Until now, meteorologists are concerned about the consequences of greenhouse effects on the climate, ignoring what happens in a natural way,” said Doug Smith, a British national weather researcher.

They tested the validity of their model by testing it over the years 1982-2001 and found that their results were much closer to the temperatures actually observed during this period than those of the previous models … Researcher of the British National Weather.

From rain to order?

Over the past several months, there has been an increasing number of announcements to cause rainfall in arid regions. In China and in Australia, there is a serious interest in the process. Explanations.

The authorities have promised, the opening ceremony of the Beijing Olympics, August 8, 2008 will not be spoiled by the rain. The very official office of the modification of time watches over it. Usually, its role is to mitigate water shortages and cause rainfall with aircraft and rockets to improve agricultural yield.

And the process is of interest to many other countries. This is the case in Australia, Queensland more precisely, where the government of the province announced on 12 July its intention to cause rainfall. Confronted for several months with the drought, The region intends to take advantage of a traditional deterioration of time in November to take off a somewhat special bomber plane.

The mission of the aircraft will be to dump silver iodide dust near the clouds. These chemical particles would accelerate the condensation and thus cause precipitation. The principle is not new. It has already been tested several times without really being able to measure its real influence. “Apart from the dissipation of fog, the artificial modification of time is still in the field of research,” Jean-Pierre Chalon, director of the National School of Meteorology in Toulouse, told
