seasonal maximum

Based on the data of annual and seasonal mean air temperature, minimum and maximum air temperature and precipitation at eleven meteorological stations in Hainan Island from 1961 to 2002, the climatic change of Hainan Island is analyzed.

利用1961～2002年海南岛11个气象站各季和年的平均气温、平均最高气温、平均最低气温、降雨量等资料，对海南岛近42年的气候变化作了较全面的分析。

The lunar atmospheric semidiurnal tide at middle and lower thermosphere ( MLT) over Wuhan has seasonal and height variations. Both of the eastward and northward components of the lunar atmospheric semidiurnal tide reach the maximum values in January, and during July-August, there is secondary peak.

武汉中层和低热层的大气太阴半日潮汐有季节变化，东向和北向分量均在1月份有最大值，在7-8月份期间，有次最大值。

It is indicated from the direct day-today comparison of the simulated and observed daily maximum/ minimum surface air temperature ( Tmax/ Tmin) and total downward shortwave surface flux in Beijing station that PRECIS possesses strong capacity to simulate the seasonal cycles of these variables;

选择典型的观测站点北京模拟的日最高/最低气温、太阳短波总辐射和月均降水量与观测结果进行直接比较，显示：PRECIS具有很强的模拟地面气候季节变化的能力。

The seasonal variation is largest in mid-latitude of north hemisphere and the maximum value happens in boreal summer.

其中，北半球中纬度陆地区域碳通量季节内变幅最大，且碳汇量最高值出现在夏季。

Orientation is frequently planned to take maximum advantage of daily and seasonal variations of sunlight.

建筑朝向的设计常以能最大限度地利用日照在日间和季节上的变化为依据.
