Secular changes of the standing circulation
Abstract The evidence produced seems to show a secular intensification of the North Indian summer‐monsoon low. The effects upon rainfall in North India and the Peninsula are discussed qualitatively. The secular decrease of the mean summer pressures in North India was associated with an increase of w...

An intensification of the standing circulation of the northern hemisphere may have caused an increased transport of warm air into the Arctic and hence contributed to the retreat of the arctic ice. The absence of large‐scale standing oscillations in the southern hemisphere, accounts, probably, for the apparent absence of marked climatic change in the Antarctic. The strength of the standing monsoon‐type circulations appears to be in a roughly inverse relation to the strength of the zonal circulation.
