The disappearance of ozone over the South Pole may be the cause of the temperature increase reefer trailer at the beginning of summer in South Africa, which has been for twenty reefer trailer years. This, scientists reported recently in an article published in Nature Geoscience [1].
Manatsa Desmond (Desmond Manatsa), a climate scientist at the University of Bindura, Zimbabwe, and colleagues analyzed data from the climate of southern Africa for 1979 - 2010, covering the period before and after the growth of the ozone hole over Antarctica. They found that the size of the ozone hole in some way affect the circuit winds and causes a jump in temperature in early summer. reefer trailer
Manatsu puzzled sharp seasonal increase in surface air temperature in South Africa. reefer trailer "The temperature [in this period] was significantly higher than in other seasons and nature of its growth was more like a sudden jump rather than on a smooth and gradual change," - he said. This coincided with the warming effects reefer trailer of greenhouse gases, reefer trailer which he expected to see.
Prior research by other scientists discovered that the ozone hole over Antarctica has changed Surface climate in Antarctica and the Southern Ocean, as well as in New Zealand, Patagonia and southern Australia. [2] Manatsa showed that the effect of the ozone hole to climate reefer trailer much more.
"The ozone hole was the dominant feature of the Southern reefer trailer Hemisphere," - said Ted Shepherd (Ted Shepherd), atmospheric scientist with Redinzkoho University, UK. "At first we thought that this effect is limited to middle or higher latitudes, but becomes increasingly clear that the lower latitudes are also exposed to it."
The size of the ozone hole varies throughout the year: in the spring becomes larger and causes the stratosphere over the polar regions cool. This shifts the cooling zone of strong westerly winds that circled closer to the pole, and therefore affect neighboring system pressure.
Manatsa found that periods of greater ozone hole coincide with increased pressure lowering continental summer, known as angels reduction, which brings warmer air from lower latitudes in southern Africa and surface air temperature increases.
Anthropogenic chemicals - freon - into the atmosphere reefer trailer from aerosol cans, air conditioners and refrigeration units and destroy ozone in the stratosphere. The Montreal reefer trailer Protocol of 1987 prohibited the release of such substances, trying to reduce the rate of thinning of the ozone layer. Atmospheric observations show that the ozone hole, which reached maximum area in 2006 (28.5 million square kilometers), now tends to decrease and some research has gone into the year 2065.
If this happens, the temperature drops in South Africa. "In my opinion, long-term projections for this region - not only air temperature near the surface, but summer precipitation reefer trailer - you will see" - said Manatsa.
