坡面日出日没时角的配置关系与太阳赤纬 总被引：3，自引：1，他引：2
若坡面的坡向β和纬度φ满足条件| sinβcosφ|≥sin 23°26',则坡面日出日没时角的配置关系不随太阳赤纬的变化而变化;反之,则存在两个绝对值相等、符号相反的一般临界赤纬δc,以-δc、δc为界,坡面日出日没时角的配置关系具有三种不同的形式。坡面日出日没时角的配置关系及其随太阳赤纬的变化,可根据δ=δc时,非水平面日出日没时角和水平面日出日没时角的相等关系、坡向、坡度确定。在水平面或非水平面极昼、极夜前后,坡面日出日没时角的配置关系也会发生变化。 相似文献

贵州高原复杂地形下月平均日最高气温分布式模拟 总被引：4，自引：1，他引：3
在前人研究的基础上,对以前的模型进行改进,考虑了坡度、坡向和地形相互遮蔽作用对复杂地形下天文辐射的影响,基于数字高程模型(DEM)数据,建立以天文辐射为起始数据的复杂地形下月平均日最高气温的分布式模型,在模型中考虑了海拔高度、复杂地形下太阳总辐射、日照百分率对月平均日最高气温的影响.以贵州高原为例.应用100m×100m分辨率的DEM数据.1960-2000年贵州省及周边102个气象站常规气象要素观测资料以及NOAA-AVHRR观测资料,10个气象站的太阳辐射量资料,计算了贵州高原各月及年平均日最高气温精细空间分布.结果表明:(1)坡度、坡向、地形遮蔽对月平均日最高气温的影响较大,由于局地地形因子的影响,复杂地形下月平均日最高气温的空间分布具有明显的地域分布特征,局地地形对月平均日最高气温的影响是不容忽视的.(2)季节不同,局地地形因子对复杂地形下月平均日最高气温空间分布的影响不同,冬半年大于夏半年.月平均日最高气温随海拔高度的增加而降低.南坡随坡度的增大而升高:北坡随坡度的增大而降低.在坡向影响上,1-5月、10-12月偏北坡月平均日最高气温偏低,偏南坡月平均日最高气温偏高;7-8月因太阳高度较高,因此出现相反的情况.北坡高于南坡. 相似文献

坡面对全球可照时间影响的解析研究 总被引：2，自引：2，他引：0
根据坡面日出日没时角配置关系及其变化规律可得到在全球坡面可照时间的具体计算公式,它们是太阳赤纬、坡度、坡向和纬度的函数。根据各种情况下坡面可照时间对坡度或坡向的偏微分可以证明,全球的坡面可照时间总是随坡度的增加而减少或保持不变,而全球坡面的可照时间随坡向的增加则是或增加、或减少、或不变,并在一定条件下存在使坡面可照时间有极大值和极小值的坡向,这些坡向是纬度、太阳赤纬和坡度的函数。 相似文献

本文首次计算并分析了我国亚热带东部山区坡面辐射平衡各分量，重点讨论了净辐射的地理分布特征及其变化规律。结果表明，本区各坡向年均净辐射的分布都具有南北高、中间低的特点、湘鄂西部为最低值区。夏季因受副高控制的影响，净辐射分布形势差别较大。净辐射在各坡向间的差异以冬季最大，夏季最小。夏季南、北坡净辐射随坡度的变化形式基本相同，冬季则安全相反。净辐射的年变幅以南坡最小、东、西坡次之，北坡最大。本文计算结果还揭示出冬季在本地区北坡的面净辐射可出现包值的新事实。 相似文献

中国三种太阳辐射起始数据分布式模拟 总被引：2，自引：1，他引：1
天文辐射、干洁大气总辐射和湿洁大气总辐射是太阳辐射模拟的3种重要起始数据。依托Iqbal Model C和起伏地形下干/湿洁大气总辐射模型,实现了水平面和起伏地形下干/湿洁大气总辐射分布式模拟。以DEM数据作为地形的综合反映,结合常规气象资料,计算了水平面和起伏地形下中国1 km×1 km分辨率日天文辐射量、干洁大气总辐射量、湿洁大气总辐射量的空间分布,并对3种太阳辐射起始数据的时空分布特征做了对比分析。结果表明：3种辐射量均遵循随纬向变化的宏观分布规律;水平面干/湿洁大气总辐射量的分布体现了海拔的影响,水平面湿洁大气总辐射量的分布还体现了水汽分布的影响;起伏地形下的3种辐射量能很好的体现坡度、坡向和地形之间相互遮蔽等局部地形特征对辐射量的影响;以干/湿洁大气总辐射作为起始数据,将有助于提高太阳总辐射的模拟精度。 相似文献

对等辐照方位与建筑朝向的选择 总被引：3，自引：0，他引：3
本文计算并分析了墙面可照时间和天文辐射日总量及其随坡向的分布,从中发现,存在东西对称的方位,在该方位上墙面的可照时间或天文辐射日总量在冬夏半年各自对应的太阳赤纬时都相等,称之为对等日照方位和对等辐射方位,统称为对等辐照方位,并且,在对等辐照方位以南的各方位上冬半年的可照时间（天文辐射日总量）大于夏半年对应太阳赤纬时的值,而对等辐照方位以北各方位的情况相反,因而对等辐照方位可作为适宜建筑朝向选择的临 相似文献

秦岭太白山气温直减率时空差异性研究 总被引：12，自引：3，他引：9
在评估山地生态系统对气候变化响应的过程中,作为气温要素的重要输入参数,气温直减率（γ）的精确性直接影响到相关科研工作的真实性和可靠性。本文基于秦岭主峰太白山（3771.2 m）11个分布于南北坡和不同海拔的标准气象站点2013-2015年连续3年实测日均温资料和25 m×25 m空间分辨率的DEM数据,研究了太白山气温直减率在不同时间尺度上的变化规律及不同坡向上的空间分布特征。结果表明：① 2013-2015年太白山年均γ北坡均大于南坡,北坡为0.513 ℃/100m,南坡为0.499 ℃/100m;北坡年均γ随海拔变化表现出一定的差异性,而南坡相对稳定。② 年内γ在不同时间尺度上均存在明显差异,且南北坡变化趋势不一致。在季尺度上,γ最大值北坡为夏季,为0.619 ℃/100m,而南坡最大出现在春季,为0.546 ℃/100m,最小值均为冬季,南北坡分别为0.449 ℃/100m和0.390 ℃/100m;春季和夏季,北坡γ均大于南坡,而冬季相反,北坡小于南坡,秋季几乎无差异。在月尺度上,气温相对高的月份γ亦较高,北坡γ变化幅度大于南坡;年始和年末（11-12月、1-2月）北坡γ小于南坡,而5-9月北坡大于南坡,且南北坡γ相差较大。③ 经数据可信度分析,所获得的γ可较为客观地反映太白山气温随海拔变化的规律性,将为山地气温空间分布规律及其生态系统响应等定量研究提供理论基础。 相似文献

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing. 相似文献
