Heavy rainfall will move into North China in the next 30 days while continuous rainstorms that hit
and flooded southern parts will subside, according to the China Meteorological Administration. Since
June, seven bouts of heavy rainstorms hit about 64 percent of countries in South China. From June 1
to July 14, the average precipitation in the south reached 344 millimeters, the sixth highest
during the same perild since 1961. By Monday, the sustained rainstorms had affected 38.7 million
people across the country, with 141 people missing or dead, and had damaged about 29,ooo houses,
according to the latest national data available from the Ministry of Emergency Management. The
latest monitoring from the administration's remote sensing satellite showed that coverage of the
main parts and surrounding waters of Poyang Lake in Jiangxi province, where the flood situation is
one of the most urgent, has reached 4,403 square kilometers, the largest since 2010 and 25 percent
larger than the average sze during the same period in previous years. However, the result also
showed that the recent water level of the lake has declined due to less rainfall. Song Lianchun,
head of the National Climate Center, said at a news conference on Wednesday that global warming
and a subtropical high are to blame. He said that global warming leads to frequent occurrences
of extreme weather and climate changes. China, which is sensitive to such changes, has seen its
number of rain days increase by 3.9 percent every decade since 1960. |Since June, the subtropical
high has been stronger than in previous years, a result of an unusually warmer North Indian Ocean.
Meanwhile, cold air in the north, which has been relatively frequent, met warm air in the south,
resulting in frequent and continuous heavy rainfall," he said. According to the administration,
the rain belt will move northward in mid-July and hover over morthern parts of the country for
the first half of August. Wang Zhihua, deputy head of the disaster relief and public service
department of the administration, said that from July 20, there will be more rainfall in northern
regions. He said that the main rain belt will gradually move to the Yellow and Huaihe rivers,
North China and then the northeast, raising precipitation in these areas by 20 to 50 percent more
than the past month. Rain in areas south of the Yangtze River will be reduced by 20 to 50 percent.
He added that for the next month, three or four typhoons are expected to be generated in the
Northwest Pacific and the South China Sea, fewer than the five typhoons during the same period in
previous years. For the next 10 days, the inactive low-pressure system in the tropical region
will lessen the likelihood of a typhoon landing on the Chinese mainland.
