walker river 中文意思是什麼
walker river
解釋
不定床河流-
When the spatial pattern is uniform in the whole area, there is a better relations between the wp ssta and walker circulation, hadley circulation, enso and the summer rainfall of the upper and middle reaches of the yangtze river, while the spatial pattern is of the north - south asymmetry, there is a better relation between the wp ssta and hadley circulation and the summer rainfall of the middle and lower reaches of the yangtze river
暖池區ssta不同分佈型與東亞大氣環流和中國夏季降水關系不同， ssta的一致性分佈與hadley 、 walker環流、 enso循環及長江中上游地區降水關系較好，而ssta南北反對稱分佈與hadley環流和長江中下游地區降水關系較好。 -
Results show that there are two main spatial patterns of the wp ssta : one is uniform in the whole area, the other is of the north - south asymmetry. when the spatial pattern is uniform in the whole area, in the warm years, there is a anticyclone circulation existing over the warm pool and westerly in the subtropical region and easterly in the tropical region have been greatly strengthened at 850hpa, while a anticyclone circulation over the india region at 200hpa, the walker circulation has been strengthened, the summer rainfall may be above normal in the upper and middle reaches of the yangtze river, vice versa
當ssta為一致性分佈時，暖異常年， 850hpa暖池區上空為一反氣旋偏差環流，副熱帶地區西風和低緯度地區東風得到加強，長江中上游地區盛行偏南風氣流； 200hpa南亞上空為一反氣旋偏差環流，長江中上游地區為北風； walker環流加強，副熱帶高壓偏強，經向垂直環流在25 35 n附近為上升氣流，長江中上游地區降水偏多，是lanina事件的多發年，對應的soi指數偏高，冷異常年則相反。
