| 摘 要： | 利用球圈范围的初始方程模式，就１９９１年太平洋主要海温异常区对降水的影响进行了数值试验，并对影响机制进行了讨论。结果表明，海温异常对降水的影响主要局限在热带和副热带地区。海温异常的直接影响是改变海气之间的感热和水汽交换，而后通过温度场和流场的变化以及凝结反馈过程影响降水。

| Abstract: | Using a primitive equation model with a spheric band domain,a numerical study iscarried out of the effect on rainfall of 1991 Pacific SST anomaly in the leading region with theaffecting mechanisms investigated.Evidence suggests that the SST abnormality has its impactconfined largely to tropical and subtropical latitudes,and its direct influence is to mtxlify the sea-air exchange of sensible heat and water vapor,causing the variation in the temperature and flowfields and condensation feedback that will modulate precipitation pattern. |
