| Abstract: | Global climate was obviously warm in 2007, and is the seventh warmest
year on record. A La Ni?a event came into being since August 2007. In th
e beginning of 2007, strong cold waves and snowstorms raided Northeast China, Japan, USA
and Canada, respectively. During boreal summer, heat wave swept East Asia, Sout
h Asia, central-southern Europe and USA. In the year, severe drought occurred in
southern China and southeastern USA; floods occurred in South Asia, and rainsto
rm attacked many countries in Asia and South America frequently. In 2007, activi
ty of typhoon was near normal in the northwestern Pacific, but stronger and more
destructive than normal. Meanwhile, activity of hurricane was less than normal
in the eastern Pacific and also near normal in the Atlantic Ocean. |
