【摘要】 该文应用Sen Z.的游程理论和方法,分析了冬季(11月-3月)寡照的游程特征量和分布参数在河南省内的分布状况,并研究了连续阴天达7d以上的概率分布,以期为日光温室避抗低温寡照灾害的气象条件分析提供依据。更多还原

【Abstract】 Using the Sen Z. ’s run theoretical model, the paper studied the runs features of low temperature and overcast days during the winter period from November to March of the next year. It also analyzed the distribution characteristics of the run distribution factor K and the probabilities of above-7-day successive overcast. The results can be used to guide the prevention or fighting against the low temperature and solar radiation shortage.更多还原
