Abstract

The heat island effect for San Antonio, Texas W.F. Huebner, B.C. Boice Southwest Research Institute, 6220 Culebra Road, PO Drawer 28510, San Antonio, Texas 78228-0510, USA ABSTRACT A preliminary study of the heat island effect was carried out comparing 45- year daily temperature records of San Antonio (International Airport) with the relatively small town of New Braunfels, Texas. It shows that, on the average, the minimum temperatures at the San Antonio International Airport are increasing at a rate of about 1±0.2°F every 15 years relative to the surrounding country site (New Braunfels). The effect is most noticable during the hot season of the year. In 1946, the difference in minimum temperatures between San Antonio and New Braunfels was much less than 0.5°F. In 1990, it had grown to about 3°F. Similarly, on the average, the maximum temperatures at the San Antonio International Airport are increasing at a rate of about 1±0.3°F every 15 years during the warm months and
