基于MODIS数据反演得到Mackenzie河口2007年8-9月海洋表面温度分布，结合该河口Pelly气象站实测风速、风向数据，分析Mackenzie河口水域的上升流特点，重点分析上升流的产生条件、发展、强度，以及它们随纬度、风向及风速的变化关系。结果表明：当东向风(160o~200o)吹刮时间长于半天时，即有上升流产生，且东风时(180o)最强烈；东向风持续吹刮时，风速越大，上升流现象越强烈、影响范围越广。
基于MODIS數據反縯得到Mackenzie河口2007年8-9月海洋錶麵溫度分佈，結閤該河口Pelly氣象站實測風速、風嚮數據，分析Mackenzie河口水域的上升流特點，重點分析上升流的產生條件、髮展、彊度，以及它們隨緯度、風嚮及風速的變化關繫。結果錶明：噹東嚮風(160o~200o)吹颳時間長于半天時，即有上升流產生，且東風時(180o)最彊烈；東嚮風持續吹颳時，風速越大，上升流現象越彊烈、影響範圍越廣。

Based on remote sensing data from a moderate-resolution imaging spectroradiometer, the sea surface temperature ( SST) of the Mackenzie Estuary in August and September of 2007 was obtained using MODIS data, and the characteristics of the upwelling phenomenon, especially the relationships between the generation, development, strength of upwelling, the latitude, wind direction, and wind speed were analyzed, combined with the wind factors at the Pelly Station during this period. The results show that, when the easterly wind (160o-200o) lasts more than half a day in the summer, upwelling will appear, and it will be strongest with an easterly wind direction of 180o. The upwelling will be stronger and affect a wider range when the wind speed is higher.
