住宅区除了受大气候影响外,还受到地方气候和住宅小气候的影响。小气候对人体健康和节能有直接影响,因此,在选择居住场所时,必须全面考察当地的气候条件,它包括日照、湿度、风、降水、雷电等5个气象要素。  相似文献   

江苏省日照时数的气候特征分析   总被引：15，自引：7，他引：15       下载免费PDF全文

沈瑱  曾燕  肖卉  费松 《气象科学》2007,27(4):425-429

利用江苏省内66个气象站1960—1999年日照时数实测资料,分析了江苏省日照时数的气候变化趋势。结果表明,就整个江苏省平均而言,尽管在1960—1999年期间,省内年平均温度升高了0.6℃,但日照时数却呈明显的下降趋势;20世纪80—90年代年平均日照时数较60—70年代的平均值下降了164.7 h,下降幅度为7.35%;日照时数的下降主要表现在夏季和冬季,秋季和春季不明显;对日照时数气候变化的空间分析表明,局部地区与整个省域的气候变化趋势并不完全同步,大部分地区是下降的,个别地区则是上升的。  相似文献

Testing the Ability of Numerical Model to Simulate Climate and Its Change With 4D-EOF Analysis     

ZHAO Deming  SU Bingkai  TANG Jianping 《Acta Meteorologica Sinica》2007,21(2):179-191

The four-dimensional empirical orthogonal function (4D-EOF), which in reality is a simple combination of three-dimensional EOF (3D-EOF) and extended EOF (EEOF), is put forward in this paper to test the ability of numerical model to simulate climate and its change. The 4D-E0F analysis is able to reveal not only the horizontal characteristic pattern of analyzed variable, and its corresponding annual and inter-annual variations, but also the vertical structural characteristics. The method suggested is then used to analyze the monthly mean 100-, 500-, 70G-, and 1000-hPa geopotential height fields (4941 grids and grid spacing 60 km) and their anomaly fields in 1989-1998 simulated by the MM5V3 from the RMIP (Regional Climate Model Inter-comparison Project for East Asia)-II, as well as their counterparts (used as the observed fields) from the NCEP/NCAR re-analysis dataset in the same period. The ability of MM5V3 in simulating East Asian climate and its change is tested by comparing the 4D-EOF analysis results of the simulated and observed datasets. The comparative analyzed results show that the horizontal pattern of the first eigenvector of the observed monthly mean geopotential height fields and its vertical equivalent barotropic feature were well simulated; the simulations of the first two eigenvectors of the observed monthly mean geopotential height anomaly fields were also successful for their horizontal abnormal distributions and significant equivalent barotropic features in the vertical were well reproduced; and furthermore, the observed characteristics, such as the variation with height, the annual and inter-annual variations of the monthly mean geopotential height/anomaly fields were also well reflected in the simulation. Therefore, the 4D-EOF is able to comprehensively test numerical model's ability of simulating the climate and its change, and the simulation ability of MM5V3 for the climate and its change in East Asia in the 1990s was satisfactory.  相似文献   

Influence of the Atlantic Multidecadal Oscillation on the Winter Climate of East China   总被引：11，自引：0，他引：11  

李双林 《大气科学进展》2007,24(1):126-135

The Atlantic Multidecadal Oscillation （AMO）, the multidecadal variation of North Atlantic sea surface temperature （SST）, exhibits an oscillation with a period of 65-80 years and an amplitude of 0.4℃. Observational composite analyses reveal that the warm phase AMO is linked to warmer winters in East China, with enhanced precipitation in the north of this region and reduced precipitation in the south, on multidecadal time scales. The pattern is reversed during the cold phase AMO. Whether the AMO acts as a forcing of the multidecadal winter climate of East China is explored by investigating the atmospheric response to warm AMO SST anomalies in a large ensemble of atmospheric general circulation model （AGCM） experiments. The results from three AGCMs are consistent and suggest that the AMO warmth favors warmer winters in East China. This influence is realized through inducing negative surface air pressure anomalies in the hemispheric-wide domain extending from the midlatitude North Atlantic to midlatitude Eurasia. These negative surface anomalies favor the weakening of the Mongolian Cold High, and thus induce a weaker East Asian Winter Monsoon.  相似文献
