Unusual Weather Changes
Recently, unusual weather changes in Korea have been on the rise. In the summer of 2002, Tropical Storm Rusa brought tragedy to 210 lives and 5 trillion won worth of property damage. In two other examples, the number of sunlight hours in Korea is not half of an average year, and the number of rainy days per month in Seoul is only 26 days.
Annually, the number of unusual weather changes are increasing as well as the damage they inflict. For example, the first extreme drought in 90 years came in 2001 and the heaviest snowfall in 20 years in 2000. Finally, due to the desertification in northern China near the Gobi Desert, the seasonal yellow sand phenomenon is steadily worsening.
Korea is not the only country suffering from unusual weather changes. In June of 2002, China was affected by a downpour that brought 500 mm of rain per day. In Eastern Europe, the heaviest downpour in 100 years flooded Prague and Salzburg and overflowed the Elbe river in Germany. In Russia, the first flood in 10 years occurred in the middle of August, so .93 people were killed and many affected including the collapse of two dams. India, Nepal, Bangladesh, and many other countries in South-East Asia have also felt the negative effects of heavy rains.
On the other side of the spectrum, the USA was recently afflicted by one of the worst droughts since 1732. The state of South Carolina has not received any rain whatsoever in the month of August for the past five years.
Like floods, heavy rains, heavy snowfalls and droughts, bad weather is also related to climate change. If the average temperature increases, vapor flows into the atmosphere. It causes powerful and localized bad weather. Actually, the inflow of vapor is processing rapidly and according to the USA and Europe, the recent concentration of vapor in the atmosphere has increased about 10~20%. From now on, we can expect that global warming will incite unusual weather such as drought, flooding and heavy snowfalls.Simply, dry areas will become drier and areas prone to habitual flooding will experience more flooding. Hence, the phenomenon of polarization will be deepened.
