Abstract

The recent trend of declining winter and spring snow cover over Eurasia is causing a land-ocean thermal gradient that is particularly favorable to stronger southwest (summer) monsoon winds. Since 1997, sea surface winds have been strengthening over the western Arabian Sea. This escalation in the intensity of summer monsoon winds, accompanied by enhanced upwelling and an increase of more than 350% in average summertime phytoplankton biomass along the coast and over 300% offshore, raises the possibility that the current warming trend of the Eurasian landmass is making the Arabian Sea more productive.

摘要

欧亚大陆冬春积雪覆盖面积近期呈下降趋势，正形成一种陆海热梯度，这对增强西南（夏季）季风特别有利。自1997年以来，阿拉伯海西部的海面风一直在增强。夏季季风强度的这种增强，伴随着上升流增强以及沿海地区夏季浮游植物平均生物量增加超过350%，近海增加超过300%，这增加了一种可能性，即当前欧亚大陆的变暖趋势正使阿拉伯海的生产力更高。
