[email protected]. AN ABSTRACT OF THE THESIS OF Li-min Yang for the Master of Science in Geography presented August 13, 1987. Title: Spatial and Temporal Characteristics of Surface Air Temperature For Portland, Oregon APPROVED BY MEMBERS OF THE THESIS COMMITTEE: · ou sen Josewr Por, _ This study examines the spatial and temporal characteristics of the surface air temperature in Portland, Oregon. Spatial temperature patterns indicate that the dominant control factors on seasonal temperature distribution are local topography, elevation, and urban-rural differences in surface structure. A heat island exists in the Portland area; the intensity of the heat island rang€s from 4° to 10° F, and varies throughout the year. The strongest heat island is found in the July minimum temperature. Temperature distribution in 2 Portland and the adjacent area is affected by winds and rainy conditions, but less influenced under overcast skies.
