ABSTRACT: This study
evaluated the behavior of surface heat fluxes, in the meteorological and
physical conditions of the Riobamba city (height of 2754 m regarding the sea
level, geographical position 1°58'58'' Sour of latitude and 78°39'33'' West of
longitude, and it is located in the Ecuadorian inter-Andean alley), these
meteorological data were monitored at the ESPOCH stations of the alternative
energy group during 2010-2012, and applied information processing dynamic model
formulated by Van Ulden and Hostlag, which allows the determination of heat
flow of sensible heat, latent heat and surface heat generated in the
interaction soil-air. The measures allow us to know the average behavior of the
heat flow data with variation between, 38.22, 22.15 and 155.20 W/m2 for the latent, sensible and surface heat respectively, while during the day
hours significant variations in these flows that reach maximum values during
the day with 139, 127 and 763 W/m2 and minimum at the night -3.9, -27.5
and -263.3 W/m2; results differ from those obtained under normal conditions
at sea level.
