Estimates for regression relationships between characteristics of tropical cyclones and gravity anomalies

Abstract

We have obtained regression relationships between vertical components of gravity anomalies in tropical cyclone areas and some cyclonic characteristics. These regressions are more pronounced in territories where negative gravity anomalies are prevalent. Numerical experiments are performed for the cyclonic zone of the northwestern Pacific and western Atlantic. In the zone of the western Atlantic, the main focus is on cyclones entering to the terrestrial part of the United States. We conclude that under some conditions, gravity anomalies can affect the characteristics of tropical cyclones.
