冬季亚洲高压的中心位置何在?

WHERE IS THE CENTER LOCATION OF ASIAN HIGH PRESSURE IN WINTER?

本文在综合分析了目前应用的几种气压场订正方法后,指出了这些方法在高海拔地区应用时的不足,提出在高海拔地区应用"保风投影法"更能准确地分析海平面气压场。作者用此方法分析了冬季亚洲高压,结果表明:在冬季整个蒙古高原、青藏高原和黄土高原为高压控制,但高压中心不象以前的气候图那样只有一个而是分裂为3个,其中最强中心位于青藏高原主体南部,另外两个中心较弱,一个位于蒙古西北部,一个位于祁连山地区。因此作者认为应将"蒙古高压"改称为"亚洲高压"或"高原高压"更符合实际。

After a comprehensive analysis on pressure reduction methods being used at present, some shortcomings of the methods had been pointed out when these methods were used in high altitude area. And the writer proposed a 'wind-conserved projection method' to analysize sea-level air pressure field is more accurate. This method was used to analysize Asian high in winter. The result shows that Mongolian Plateau, Tibetan Plateau and Loess Plateau are under the control of high pressure with three centers in winter, the highest center is on the south part of Tibetan Plateau, and the other two centers locate on northwest part of Mongolia and Qilian mountain area, respectively. Based on the result above, the writer proposed that it is more reasonable to call 'Mongolian high' as 'Asian high' or 'Plateau high'.
