| 摘 要： | 本文利用改进的Ｔ４２Ｌ９模式，以１９７９年６月１４日１２时的ＦＧＧＥ－Ⅲｂ资料为初始场，分别在有地形非绝热，有地形绝热以及无地形绝热情形下进行了五天数值预报试验，研究了青藏高原的热力和动力作用对高原东北侧干旱天气的影响，模拟结果指出，在初夏夏季风爆发期间，青藏高原有利于其东侧（包括甘肃南部和陕西南部一带）进入雨季，但也有利于其北侧的河西走廊地区维持干旱，高原的动力和热力作用对高原北侧的初夏干旱天气有着重要的影响。

| Abstract: | Using the FGGE-IIIb data covering period from 14 June to 19 June 1979, the dynamic and thermodynamic influences of the Qinghai-Xizang Plateau on the drought weather in its northeastern side are physically investigated employing a general circulation model (T42L9) with a improved cloud-radiation scheme. By virtue of the five-day prediction experiments, with and without the inclusion of mountain and / or diabatic heating effects, it is found that the influences of Qinghai-Xizang Plateau are very significant for its northeastern drought-weather, and also for its eastern monsoon rainfall in the early Summer. |
