Progress of Large-Scale Air-Sea Interaction Studies in China

This paper summarizes the progress of large-scale air-sea interaction studies that has been achieved in China in the four-year period from July 1998 to July 2002, including seven aspects in the area of the air-sea interaction, namely air-sea interaction related to the tropical Pacific Ocean, monsoon-related air-sea interaction, air-sea interaction in the north Pacific Ocean, air-sea interaction in the Indian Ocean, air-sea interactions in the global oceans, field experiments, and oceanic cruise surveys. However more attention has been paid to the first and the second aspects because a large number of papers in the reference literature for preparing and organizing this paper are concentrated in the tropical Pacific Ocean, such as the ENSO process with its climatic effects and dynamics, and the monsoon-related air-sea interaction. The literature also involves various phenomena with their different time and spatial scales such as intraseasonal, annual, interannual, and interdecadal variabilities in the atmosphere/ocean interaction system, reflecting the contemporary themes in the four-year period at the beginning of an ara from the post-TOGA to CLIVAR studies. Apparently, it is a difficult task to summarize the great progress in this area, as it is extracted from a large quantity of literature, although the authors tried very hard.

Impact of Abnormal Climate on Agriculture in Fushun City in 2010

[Objective] The aim was to study the influence of abnormal climate in Fushun City in 2010 and its influences on agriculture.[Method] In response to the abnormal climate in Fushun in 2010,the atmosphere circulation characteristics of abnormal climate and their influences on each aspect of agriculture were expounded.[Result] The abnormal weather in Fushun City in 2010 was as follows:extreme low temperature in spring,much precipitation,more precipitation in each month,less sunshine hours,abnormally less precipitation in July and August,having five times of heavy rain.The main atmosphere circulation features were extreme strong of vortex in March and frequent cold air activity;strong high pressure ridge in Mountain Ural in Middle April,west and strong east Asian Trough and strong front in middle and north part of Asia;middle and high latitude in Asia in May was wide trough region.The subtropical high ridge of the north front was more north than that in other common years and the position of west ridge was more conductive to the transportation of water vapor and formation of rain;because of extreme strong vortex in July and August,subtropical high was conductive to the cold air in the north moving south and the transportation of south water vapor.The extreme climate brought adverse influences on each aspect of agriculture and resulted into large economic losses.[Conclusion] The study provided references for the improvement of abnormal climate forecast and disaster prevention capacity.
