Emerging solar polar magnetic field regime has a significant influence on the profile of cosmic ray 11-year modulation. Our conclusion is derived from an analysis of the shielded ion chamber data obtained at Cheltenham--Fredericksburg (1937--1974) and Yakutsk (1957--1990) and of neutron monitor data obtained at Huancayo (1953--1992), Climax (1951--1992), Ottawa (1954--1959), and Deep River (1960--1992). The recovery of cosmic ray intensity follows two distinct patterns. During odd solar activity cycles (17, 19, 21) when the magnetic polarity of the Sun in the northern hemisphere is negative (qA0 the recovery period is reduced to less than half as much. The rapid recovery seems to set in following the reversal of solar polar field during even cycles (18, 20) unless interrupted by solar activity (as for cycle 22). The delayed rapid recovery for cycle 22 is in progress. At present, it is not clear whether the next cosmic ray maximum will follow the ''mesa'' pattern. ¿ American Geophysical Union 1994
