Perhumid climate
From Glossary of Meteorology
perhumid climate
As defined by C. W. Thornthwaite in his 1948 climatic classification, a type of climate that has humidity index values of +100 and above.
This is his wettest type of climate (letter code A) and compares closely to the wet climate that heads his 1931 grouping of humidity provinces.
