Abstract
In the atmospheric boundary layer, the air-soil interaction produces dynamic effects that affect the atmosphere, particularly the surface layer, where the most important activities of man and his environment take place; the present investigation calculates the micro meteorological parameters and analyzes their variation over time; under typical conditions of the Riobamba city, considering the effects due to its height and geographical position (2750 m and 1 ° 58`58 `` S of latitude and 78 ° 39`33 '' W of longitude), from which it follows a high regularity in behavior throughout the year, with strong convective flows, due to the high latent heat flow, which results in significant variations in the length of Obukhov, during daylight hours, and conversely, at night, it decreases becoming a stable system, which are determined using the Van Ulden and Hostlang model as a basis.
