Abstract: ECAUSE OF THE PAUCITY of upper-air data from the Pacific, one must either wait patiently or make guesses.This paper springs from the latter policy.It is frankly a speculation.It has even been called "meteorological delirium tremens.,, It is presented in the hope that it will be discussed.It may be beneath criticism but it is certainly not above it.The period, August 1 to 15, 1940, was selected for several reasons.Surface winds were east or northeast and fairly steady.Other directions were reported for only four hours at the Honolulu station of the Weather Bureau, and those were in night or morning with low velocities.In contrast to the steady surface winds, there was much variation aloft.Rainfall was frequent and abundant, with some very wet and some nearly dry days.During this period the North Pacific subtropical High divided (within the area of the maps), united, and divided again.Thus these fifteen days provided a variety of trade-wind weather types.Effort was made to assemble all pertinent information and to display it in uniform graphs.Thanks are due the Weather Bureau, Pan American Airways, the Army, and the Navy for data cheerfully supplied.None of them is in any way responsible for the speculations here set forth.The surface isobars (FIGURE 1) are generalized from Pan American maps for 0000 GCT, equivalent to 1330 Hawaiian standard time.Adiabatic diagrams, plotted from Pearl Harbor APOBs, are not reproduced here, as•Read before the Mid-Pacific Division of the American Meteorological Society, Honolulu, August 20, 1941.
