What is the minimum wind speed of a tropical depression:

A tropical depression has a minimum sustained wind speed of 38 mph (61 km/h), below which it is not classified as such. Studying this highlights its role in meteorology, the challenges of classifying weather systems, and its impact on disaster preparedness. It also offers insights into how wind speeds define storms, providing lessons on improving weather forecasting and early warning systems to mitigate the impact of tropical storms on vulnerable regions.
