Beijing saw unusually wet weather over summer

Average precipitation during Beijing's three-month flood season, June 1 to Aug 31, set a 20-year record this year, with precipitation in July alone at 400.4 millimeters, the most since 1951, according to a statement on Friday from the Beijing Meteorological Service.

The city was hit by rainfall 62 times during the three wettest months this year, a 30 percent increase over the same period last year.

The authority said most precipitation in Beijing occurred in the city's mountain areas, ranging from the middle part of the city's Fangshan district in the southwest to the mountains of Pinggu district in the northeast.

Weather forecasters said the reasons for frequent rainfall in Beijing this year include frequent cold air movement at middle and high altitudes in early July. The cold air intersected with the warm air in the North China region, which brought higher precipitation to Beijing in July.

In August, the convective weather associated with thunderstorms frequently appeared in the capital, resulting in more precipitation last month, the forecasters said.
