摘要
利用卫星观测和地面实测资料统一归算的全球空间重力异常 ,探讨重力异常对全球冬夏大气活动中心、热带气旋以及温带气旋和高原低涡多发区的影响 ,并对其物理机理作一简要讨论 .认为重力异常是大气运动发生发展不可忽视的因子之一 .
Based on information from satellite observations and surface field measurements, the global spatial gravity anomaly is calculated. Influences of the gravity anomaly on the activity center of the global atmosphere in winter and summer, tropical cyclone, extratropical cyclone, and the plateau regions incident to low whirlpool are discussed. And brief discussions of its physical mechanism are performed. It is likely reasouable that gravity anomaly is an important factor in the occurrence and development of the atmosphere activity.
