PRELIMINARY STUDY OF INDOOR FEATURES OF TEMPERATURE AND HUMIDITY FOR ROOMS FACING NORTH-SOUTH IN WINTER IN A LOW-LATITUDE PLATEAU CITY

Analyzing observations of wintertime air temperature in both indoor and outdoor surroundings in Kunming, a city lying in low latitudes, characteristics of temperature and humidity have been studied for the interior of rooms facing north-south under different weather conditions. Significant warming effect has been identified in terms of lowest and daily-mean indoor temperature in the area of Kunming. The heating amplitude ranges from 7.7°C to 10.0°C and from 4.6°C to 5.8°C for the interior part of rooms facing the south and from 4.6°C to 7.0°C and from 1.3°C to 4.4°C for the interior part of rooms facing the north, respectively for the two elements. The highest air temperature is higher indoor than outdoor for rooms facing the south, but otherwise is usually true for rooms facing the north. Additional findings point out that buildings not only help maintain relatively warm indoor temperature but delay its variation. The diurnal cycle of temperature indoor is smaller and ranges by 40% ~ 48% for south-facing rooms, and by 20% ~ 30% for north-facing rooms, than outdoor, and the highest temperature is about 2 hours late inside the room than outside. It shows how inertly indoor temperature varies. The work also finds that relative humidity is less indoor in southward rooms than in northward ones and difference is the largest on fine days but the smallest when it is overcast. For the diurnal variation, the indoor relative humidity is large at nighttime with small amplitude but small during daytime with large amplitude. The above-presented results can be served as scientific foundation for more research on climate in low-latitude cities and rational design of urban architectures.     

岷江上游雨季南北坡小气候特征比较

利用岷江上游茂县大沟不同坡向的小气候观测资料,探讨了该地区地雨季的太阳辐射、气温、地表温、水汽压、相对湿度、风速等小气候要素的南北坡特征及其与谷底的差异。通过比较分析得出:在雨季南坡的太阳辐射量大于北坡和谷底;南北坡气温、水汽压、相对湿度在昼间有一定差异;北坡气温略高于南坡;气温垂直递减率南坡(O.71℃/100m)大于北坡(O.61℃/100m)。水汽压为北坡<南坡<谷底;而相对湿度为谷底<北坡<南坡,北坡和谷底的太阳辐射、气温、地表温、水汽压最大值比南坡早出现1h。南北坡风速均大于谷底,而南坡风速又大于北坡。由此可见,岷江上游地区即使在雨季,山地对局地气候仍有一定影响。     

昆明城市发展对室内外平均气温影响的研究

利用受城市扩大影响的昆明气象站室内外气温资料和未受城市影响的太华山气象站气温资料，以及城市建成区面积和城市人口资料，分析了昆明城市发展对室内外平均气温影响程度，由于城市面积扩大导致昆明的室内外气温均升高，城市增温效应在1-4月较大，5-12月较小；城市增温效应的主要影响因子在上半年是城市人口增加，而在下半年则主要是城市建成区面积的扩大，另外，城市增温效应与城市建成区面积、城市人口均有较好地相关关系，城市建成区面积增加对平均气温的影响较大；而城市人口增加对平均室内气温的影响较大。     

哀牢山北段光资源特征初步分析

本文在分析哀牢山北段光资源随海拔和坡向变化特征时发现,与迎风西南坡比较,背风东北坡海拔1000—1900米处有一较强的年日照和太阳总幅射增加的焚风效应带,尤以海拔1500—1600米最明显,这有利于农业生产,但在>1900米处则相对较低。最后,给出日照与雨量的指数关系。     

哀牢山气温时空分布特征

哀牢山气温时空分布特征：最热月为６月，最冷月为１２月（东坡）或双月（西坡）；日平均最低气温在０７—０８时出现，日平均最高气温在１５—１７时出现；平均气温的垂直分布一般是东坡高西坡低．

启东市加强鳗鱼苗产销管理

启东市滨江临海,鳗苗资源十分丰富,通常情况下年产量为3吨～5吨,最高的1995年超过6吨,成为全省乃至全国鳗鱼苗的主产区之一。近几年,由于鳗鱼畅销,促进了养鳗业的迅速发展,于是,鳗鱼苗就自然而然地身价百倍,成为珍贵的渔业资源,被人们称誉为“水中黄金”和“软金子”,前些年,每到春暖花开时,就由此引发出一场以沿江沿海为主要     

启东市远洋渔业发展的现状、问题及对策

1 启东远洋渔业发展的基本情况 启东市远洋渔业的发展,曾先后作过三次尝试,总体状况是:起步时间较早、发展速度不快、振兴之志不减。 第一次尝试,是在1992年,启东市海洋渔业公司先后投入1 300多万元,建造了两艘750马力(8158型)的大马力渔轮。这一年的4月8日,     

河南省近10年汛期多雨时段大尺度环流特征

利用1995～2004年气象资料,分析了河南省降水最多年份汛期降水集中时段的大尺度环流特征,结果发现降水集中时段100 hPa南亚高压120°E脊线基本维持在25～32°N之间,降水集中时段开始前南亚高压有一个东移北跳过程,降水集中期间100 hPa高度场上呈现东高西低形势,有利于副高西伸和北抬;西太平洋副热带高压相对稳定,在多雨时段副高进退次数较多,且较长时间稳定在25°N左右,有利于西南暖湿气流沿副高外围进入河南省境内,为暴雨提供了充足的水汽;在降水集中时段,中纬度西风急流轴位置被北抬到40°N 以北,40°N以南基本是东风,这种中纬度地转西风持续偏弱,有利于副热带高压北跳和北跳后稳定,使雨带稳定在河南省.
