Since may, by 2010, China southern provinces suffered severe storms and floods hit rounds. Compared with the year, most of northern China, jiangnan rain more than 20%, jiangxi, fujian, guangdong, five parts into a more. In fact, the south China provinces nowcasting system is mainly due to the “North Pole vibration” phenomenon caused by cold continuous down, and added “el nino phenomenon bring – la warm moisture” flanked by “.
“The arctic climate shocks” trouble
“The arctic shock” refers to the arctic over high pressure jet, cold extrusion to farther than ever by the South Pole vibration “, “too cold, only release of bad weather.
El nino – Nina active
2009, “el nino” visit Pacific region, affected, warm air from the Pacific northwest into Chinese mainland. “La” phenomenon and bring a lot of rain.
The rain island effect is a catalyst
Heavy rain island effect “is a catalyst, high-rise city. The air circulation, air conditioning, exhaust emission increased heat over the city, the phenomenal form heat flow and heat flow accumulate more thick, cause water.
Background: global warming
Climate warming caused lots of water evaporation, increased water vapor in the atmosphere, resulting in more extreme events. Secondly, the average global temperature rise of temperature changes, also increases the probability of extreme weather.


- Flood disaster human reasons:
Prediction: the forecast accuraty to low level only 17% – 18%
Rainstorm forecast a worldwide problem, especially the quantitative, timing, designated prediction was very hard, the United States and other developed countries accurately forecast rate only 23%. At present average only 17% – 18% accuracy.

A warning not meteorological department to finish. Rainstorm warning points yellow, orange, red three. But a warning that it takes three to four hours, sometimes yellow haven’t finish, has turned to orange.
The rain will flood every city lags management deficiencies.
Mainly because of waterlogging road sclerosis “drink” no rain, others into urban drainage pipelines greatly more, more important is the city managers “, the construction of underground please gently, “management concept and function
The endless damage the ecological environment
Due to the forest, the population expansion, to the lake, excessive deforestation, vegetation, reduce lakes, rivers predatory activities such as occupation, causing the destruction of ecological system, and increased risk of flooding
