| Summary: | Average characteristics of subsidence inversions associated with
the Pacific High have only been documented for areas along the U.S.
West Coast and over the tropical eastern North Pacific Ocean. This
study, which is based on 3414 upper-air soundings for June through
September of 1964 and 1965, shows the average summer season
characteristics of the inversion from Tatoosh Island, Washington
northward along the coast of the Gulf of Alaska. A comparison is
also made with the subsidence inversion found over the eastern North
Pacific Ocean from Johnston Island (17°N, 168.5°W) to Ocean Station
PAPA (50°N, 145°W). Some of the more notable findings are: (a) a
diurnal oscillation of the height of the inversion base exists,
except in the regions of Yakutat and Anchorage, Alaska; (b) the height
of the inversion increases with increasing latitude from Tatoosh
Island to Anchorage; (c) the inversion thickness decreases from
Tatoosh Island to Anchorage; (d) subsidence inversions are most
pronounced over the California coast compared to any other location
between Johnston Island and Anchorage. === Graduation date: 1978
