Climatic switches

Abstract

Previous studies have established that air/surface temperature variations at any location along the Earth take place in three different amplitude modulation modes (or states). In this paper we show that two of these amplitude modulation modes can be switched from one to the other by simple meteorological processes which are herein termed “climatic switches”. The two climatic switches (for a given location) specifically established and discussed here are a (sufficiently rapid) heating/warming episode and a (sufficiently rapid) cooling episode. Existence and influences of these two climatic switches are further ascertained and illustrated using climatic records from the U.K., Africa and U.S.A. It is inferred that a rapid man-created greenhouse-warming which is sufficiently large and spread along a given location may act as a climatic switch and hence a cause for climatic change in that particular location. A climatic change caused by climatic switches may involve an increase or a decrease in the average of some naturally existing temperature oscillations. This implies that climatic switches may be mechanisms built into the climatic system in order to make it wriggle temporarily out of a steadily rising (or falling) temperature trend caused by a sizeable heating (or cooling) process.
