ABSTRACT:
Objectives: As a result of global warming,
precipitation is likely to increase at certain area (high latitudes). However,
the mechanisms that human activity is influenced by global climate change are
far from completely understood. We try to analyze the relationship between
industrial emission (trace metal, nitrogen and phosphorus) and climate
signature (precipitation) by Chinese industrialization progresses. Methods:
Mainly by using the public data from Bulletin of Environment in China,
Bulletin of Marine Environmental Status of China and some data of our
experiments, we get the analyzed result. Results: Annual average temperature in
China after industrialization is significantly increased, whereas annual
average precipitation in China after industrialization is no significantly
difference. Phytoplankton increases evaporation of seawater and the relative
humidity. Phytoplankton biomass will be different in different stages of environmental
pollution in coastal areas. The higher relative humidity of Guangzhou (near the
second-third class pollution coast-Shenzhen coast with higher phytoplankton
biomass) has higher precipitation; in contrast, lower relative humidity of
Shanghai (near the inferior fouth class Zhejiang coast) has lower precipitation
recent years. Conclusions: Industrial emissions may have two competing effects:
one is to promote the growth of phytoplankton and then cause higher seawater
evaporation rates and precipitation; another is to decrease water vapour
pressure by serious pollution, which then reduces the seawater evaporation rate
and precipitation. With temperature increasing, the precipitation is likely to
increase only at low pollution area (high latitudes).
