Tropical CycloneA warm-core, non-frontal synoptic-scale cyclone, originating over tropical or subtropical waters with organized deep convection and a closed surface wind circulation about a well-defined center.
The anomalously warm water also causes the deep convection to shift from its normal position near Indonesia to the east. This is also preceded and accompanied by anomalous westerly wind at low levels.
What primarily distinguishes tropical cyclones from other meteorological phenomena is deep convection as a driving force.[22] Because convection is strongest in a tropical climate, it defines the initial domain of the tropical cyclone.
CONVECTIVE CHIMNEY - Term applied to the deep convection associated with a tropical cyclone. This region is commonly found at the core of the system and is characterized by strong updrafts.
Cumulonimbus clouds (Cb) Thunderstorm clouds that form as a consequence of deep convection in the atmosphere.
Since warm base (>10°C) convective clouds of about 2 km depth typically have these features, the warm rain process is found to be active in both shallow and deep convection in the Tropics and midlatitudes.
