 Light and variable winds cover a large area near their center, while bands of showers and thunderstorms develop within their area of circulation.The presence of an upper level jet stream poleward and west of the system can enhance its development by leading to increased diverging air aloft over the monsoon depression, which leads to a corresponding drop in surface pressure.Even though these systems can develop over land, the outer portions of monsoon depressions are similar to tropical cyclones.
