The simulated scs surface circulation is generally cyclonic ( anticyclonic ) during the winter ( summer ) monsoon period with a strong western boundary current . the surface circulation in spring and in fall possesses transitional characters between summertime and wintertime 模拟结果给出了南海环流的基本特征：西边界流、南海暖流、冬季(夏季)海盆尺度的气旋(反气旋)式环流。
Since the summer rainfall abnormality has closely relationship with both the soil moisture and temperature abnormality . we study the impact of pre - wintertime and springtime soil moisture and temperature on the summer rainfall over huai river basin 由于夏季降水异常与前期土壤温、湿异常状况都有密切的关系，本文进一步研究了淮河流域前期下垫土壤温、湿度异常对夏季降水异常的影响。
On february 8 , 2004 , fellow practitioners from the paris center extended masters wintertime love and concern to their less fortunate brothers and sisters by distributing quilts , delicious vegetarian sandwiches , hot tea and coffee and sample booklets around the city 同修们准备了50多条毛毯可口的素食三明治热茶咖啡和样书，并带着满满的师父爱心，向那些流落在巴黎街头的游民表达关怀慰问之意。
In northern european countries such as germany , homeless people are the most pitiful during the wintertime . besides enduring cold and poverty , they suffer from the loneliness and isolation of the big city . sometimes their lives are even put at risk in the freezing cold climate 像德国这些欧洲北部国家，到了冬天，无家可归的人就特别可怜，除了贫寒交迫之外，还得忍受身处大城市中的寂寞和孤离，甚至还有遭受冻毙之虞。
Aiming at the problems of lower soil temperature , which restrains plant develop in greenhouse in wintertime , with the technology of solar energy conserving in soil , it is the paper that introduces a system which is able to store solar energy in soil by a collecting and storing unit of solar energy 本文针对冬季温室地温低，严重影响作物生长发育的问题，利用太阳能地下蓄热技术提高地温，满足作物生长对温度的要求。
The experiment indicates the rate is able to meet crop requirement of yield all the year round the research accomplishes the goal of storing solar energy in summertime and utilizing in wintertime , storing in daytime and utilizing in nighttime , storing in sunshine and utilizing in cloudy sky 本文研究的太阳能蓄热系统实现了太阳能夏天贮冬天用、日间贮夜间用、晴天贮阴天用的目的，在不进行人工增温的条件下，能满足作物的冬季生长要求。
In the upper troposphere , there is no intact asian active center . the troposphere structure of summertime ao is implicated with the horizontal heterogeneity of air temperature throughout the whole troposphere with its center over asian continent , which results in the zonal asymmetry and baroclinic structure of the summertime ao ( especially its asian center ) . on the contrary , the correlation between wintertime ao and sea - land thermal contrast confines in the lower troposphere , hence its zonal asymmetry and baroclinity in the lower level 夏季北极涛动的这种结构与对流层整层的温度水平分布不均匀性有密切联系，且这种温度分布差异主要体现在亚洲大陆，因而也就使北极涛动的中纬度亚洲中心呈现出比同纬度带其它区域更为明显的纬向非对称性和斜压性；而冬季北极涛动受下垫面海陆分布差异影响，其纬向非对称型和斜压性质主要出现在对流层中低层，在对流层高层表现出很强的环形模态和正压结构。
Spatial distribution and time scales of atmospheric diffusion over beijing area are revealed by means of a random walk simulation model and practical meteorological data with a specified emission source from the city . results show a southward transport pattern for wintertime while a northwest transport of pollutants in summer . the area is the least evidently influenced by the emission source in spring , while the largest in autumn . the time spent for instantly emitted material removing from the model domain varies from winter - spring to summer - autumn . the former was shorter one of less than 20 hours ; the latter was longer one of approximately 30 hours . distribution of occurrence probability for different removal times was not symmetry . reducing slowly at the end of longer removal time , probability exists for pollutants remaining in this area a long time 结果表明，冬季示踪物偏南夏季偏西北的输送明显春季扩散影响范围最小秋季最大。示踪物从200km200km模式区域输出的平均时间去除时间明显分为冬春季和夏秋季两组，前者较小，平均在20h以下，后者较大，平均约30h 。不同去除时间出现的频率分布是非对称的，在长去除时间一侧，出现频率下降缓慢，显示污染物有在该区域内长时间滞留的可能。
A three - dimension baroclinic prognostic model on the o - coordinate is established based on pom to simulate the wintertime circulation and the eddies in the east china seas , considering the topography , inflow and outflow on the open boundary , yangtse runoff , heat flux and wind stress on the sea surface 本文在pom模式基础上，建立一个坐标系下的三维斜压预报模式，考虑了海底地形、外来流、长江径流、海面风应力、海面热通量等多方面因素的影响，模拟结果较好地体现了冬季东中国海环流及涡旋的特征。
