控制問題的降階控制器Abstract : monthly rainfall data from 1951 to 1995 for june, july and august in 13 meteorological stations of the north china were used for accounting z index and discussing serious flood and drought featureas in these months. serious flood mainly happened in july and august, and sevious drought mainly happened in august. there were more flood in 1950 ' s to 1960 ' s and more drought since 1970 ' s in the north china. meanwhile, the deeper trough which covered the regions from the ural mts. to the balkhash lake play an important role in serious rainstom in rainy season in the north china. there often happened serious flood ( drought ) when the northwester pacific subtropical high was by west and north ( east and south ), and the sea surface temperature in the equatorial central and eastern pacific was mainly in dropping ( raising ) stage
文摘:利用華北平原地區的13個站點, 45年( 1951 1995 )的降水資料,對夏季4個時段( 6月、 7月、 8月、 6 8月)進行了z指數計算,確定了該地區各個時段的嚴重澇年和嚴重旱年.發現華北地區雨季的嚴重洪澇主要集中在7 , 8月,嚴重乾旱則主要發生在8月,並可明顯看出由50 60年代的多水期向70年代中期以後的少水期的轉變,另外,烏拉爾山到巴爾喀什湖附近的低壓槽加深和西北太平洋副熱帶高壓的北抬,對華北地區雨季持續性暴雨的產生起著決定性的作用.嚴重洪澇年的夏季( 6 8月) ,西北太平洋副熱帶高壓偏西、偏北,赤道東太平洋海溫多處于下降階段;嚴重乾旱年西北太平洋副高偏東、偏南,赤道東太平洋海溫則處于上升階段According to their changes, the decaying process can be divided into 4 stages : the drastic change stage the fluctuant reducing stage the stage tending to be stable the fluctuating and rolling stage
