Tropical depression (abbreviation of tropical depression) is a kind of tropical cyclone. It belongs to the weakest level of tropical cyclone intensity (its maximum wind force is below 62 kilometers per hour). The tropical depression is composed of many upward strong convective clouds, which began with the so-called "tropical disturbance" formed by the clouds developing in the air unstable area on the tropical ocean. Tropical cyclones in the early stage of development, or when strong tropical cyclones weaken after landing, are all tropical depressions.
