Unusual climate changes in East Asia

The growing East Asian economy has caused environmental disadvantages in this region. Researchers warn that polluted clouds are formed from emissions known collectively as Aerosol, which are moving toward eastern Asia, in the Pacific region and the cause of storms.

Polluted cloud formation accumulates from many factors such as the time, quantity, and precipitation of Aerosol. While it is still in the process of research to understand the effects of the weather, previous studies have documented pollution from urban areas associated with intense thunderstorms. increasingly strong. Recorded from satellites, the East Asian pollutants are mostly burned. This has increased SO2 to 35% in the past decade.

The researchers obtained a cloud ratio between 20% and 50% between 1994 and 2005 compared to 1984 - 1994. After analysis, along with computer modeling to simulate and compare with one The storm appeared in November 2003, the results were fully compatible.

The rise of many small clouds does not conclude the robustness of abnormal weather. But combined with the humid air, and the middle-tier components of the Pacific region, has led to unusual weather developments.

Meanwhile, Climate Researcher V.Ram Ramanathan of the San Diego Oceanographic Agency, California, re-researches the dark clouds in the Pacific. These are clouds that have intensified over the past 10 years. "We are observing the effects of EL NiNo and the factors that make up the storm. At the same time, we must also consider polluting emissions," the climatologist said.

University of Hawaii meteorologist Gary Barnes agrees that polluting emissions in Asia may be adding more clouds, but he is skeptical about the combination of these phenomena in Increasing the intensity of the storm will appear. According to him, surveying the actual intensity and influence of storms only makes more confidence in analytical signals from satellite data. This will be much more convincing in the research process.
