Chinese minimum and maximum temperature fields are divided respectively by the rotted empirical orthogonal function eleven , twelve sub regions can be taken for minimum and maximum temperatures respectively 利用旋轉主分量分析,分別對我國極端高溫和極端低溫場進行了客觀區(qū)劃。極端低溫和極端高溫場分別可以分為11 、 12個變化區(qū)。
2 . doppler frequency shifting and curve fitting differential methods for measuring velocity are analyzed and compared . the least - squares curve fitting methods based on power functions and orthogonal functions are analyzed and compared 2 .對測量速度的兩種方法,多普勒頻移法和曲線擬合微分法作了分析和比較;對以冪函數(shù)族和以正交函數(shù)族為基底的最小二乘曲線擬合法作了對比分析。
With the rotational complex empirical orthogonal function rceof , we analyzed the spatio - temporal evolvement of the latest fifty years ssta of pacific ocean . came to a result that there are two strong signal center : one at middle and east pacific ocean near equator , the other at 40n . it will take several months to half a year for the signal to reach west pacific ocean from east coast of pacific ocean near equator correspond to enso 運用轉動復自然正交展開rceof分析近50年太平洋海溫場的時空結構,得出在赤道中東太平洋和40n附近有兩個海溫異常強信號中心赤道東海岸太平洋海溫異常信號對應enso信號在幾個月到半年左右傳播到赤道西太平洋海溫主要周期大部分落在310d的范圍內,還存在年和準兩年變化。
Based on the empirical orthogonal function ( eof ) , the characteristics of large scale variations of precipitation anomaly during rainy season ( from jun to aug ) in south - west china for the period 1961 1995 is analyzed , and the teleconnection distribution charac - teristics between sea surface temperature ( sst ) over india ocean and precipitation during rainy season in south - west china were studied by using the method of cca 用自然正交函數(shù)展開方法對1961 1995年西南汛期( 6 8月)降水大尺度變化特征進行分析,并在此基礎上用典型相關分析方法研究了1 8月印度洋海溫距平場與西南汛期降水場的遙相關分布特征。
