The existence of connections between the kinematic characteristics of wind (maximum speed and its acceleration) in a tropical cyclone and the values of gravity anomalies (vertical and horizontal components, respectively, VGA and GGA) along the paths of movement of tropical cyclones. It is shown that the change in VGA values is generally close in antiphase to changes in velocity and, to a certain extent, correlates qualitatively. Analysis of wind accelerations and the corresponding values of VGA did not reveal a clear match in their comparison. Changes in GGA values are close to changes in wind speed and at a qualitative level they correlate well except for the emergence of a shopping center on land and the movement of a shopping center in a highly anomalous region. Comparison of changes in maximum speed and acceleration of wind with changes in GGA values is performed for the first time.
