天氣小觀:太平洋高壓偏弱,邁向聖嬰趨勢
目前太平洋高壓的結構很差,而未來一周仍持續偏弱,
脊線均在台灣以東,因此哈隆颱風預計將在台灣東方海面北上
往日本而去。
目前整個東亞到西北太平洋的環境來看,海溫比起去年明顯偏低,
暖水區大致上都在北緯30度以南,
從西太平洋到東太平洋都出現跨赤道氣流,
中太平洋上不斷有氣旋擾動出現,
不過該區的環境不如西太平洋季風槽,發展還有待觀察。
但由於太平洋高壓偏弱,
西太平洋到東太平洋都有跨赤道西風流的出現,
使的太平洋低緯度熱帶東風偏弱,
西太平洋的高海溫區往東移,
因此,看來整個大氣環境趨向聖嬰現象發展。
太平洋高壓偏弱,相對於北方西風帶活動變得活躍,
西風波動頻繁的交換冷暖空氣,北方冷空氣無法堆積,
對南方台灣來說,北方沒有強勢的冷系統,
因此秋冬就可能偏暖,為聖嬰現象的發展趨向。
總結未來一周,太平洋高壓沒有西伸,
哈隆颱風遠海北上,颱風尾的西南氣流預報不會帶到台灣,
大致上看起來天氣還算穩定。
(快速說說,以上供參囉)
