It is found that El Nino, relative sunspot number and sub-high integrated index in west Pacific well correspond to the regularity of drought and flood.
研究发现埃尔尼诺、太阳黑子相对数、西太平洋副高综合指数与旱涝变化规律有很好的对应关系，并有很高的相关系数。
The results show: the rainfall anomalies over the sough China area tend to be positive (or negative) during the weakening periods of El Nino (Anti- El Nino) events; the rainfall anomalies in July and August t.
结果表明:华南地区在埃尔尼诺(或反埃尔尼诺)消亡阶段,降水是偏多(或少);江淮地区除7、8月份降水在(反)埃尔尼诺年是显著偏(少)多外,6月份的降水变化与东赤道太平洋SST有反相变化关系;华北地区夏季降水在反埃尔尼诺年是偏多的。
Hermite interpolation algorithm is described in IRFPA nonuniformity correction.
提出在IRFPA非均匀性校正中使用埃尔米特插值方法,与其他传统方法相比较具有运算量小,修正效果好,易于实现等优点。
