TRS Map MET

Tropical Revolving Storms affecting the USA are called hurricanes. Tropical Revolving Storms affecting Japan and the nearby areas are called typhoons. The remaining Tropical Revolving Storms are called cyclones.

In terms of the time of year, one of the prerequisites for a TRSTRS —Tropical Revolving Storm is a plentiful supply of moisture. This happens when the seas are at their warmest. This is likely to be the case after the summer (as water takes a long time to heat or cool) in the autumn seasons for that hemisphere (remember the seasons are reversed in the southern hemisphere.) This will be Jul-Oct for the northern hemisphere and Jan - Apr for the Southern hemisphere.
