Gv. Parishwad et al., PREDICTION OF MONTHLY-MEAN HOURLY RELATIVE-HUMIDITY, AMBIENT-TEMPERATURE, AND WIND VELOCITY FOR INDIA, Renewable energy, 13(3), 1998, pp. 363-380
This paper presents a procedure to predict monthly-mean hourly values
of relative humidity, ambient temperature and wind velocity for an Ind
ian location. Three maps, showing distribution of annual-average hourl
y values of humidity, temperature and wind velocities, are prepared fr
om the analysis of available meteorological data of 205 Indian cities.
An equation is obtained for annual-average temperature as a function
of altitude of the location. Sets of equations are then developed to p
redict the said weather parameters by the least square regression anal
ysis of the data of 14 cities, taken from different regions, out of 19
cities for which detailed weather data was available. A ratio of mont
hly-mean to the yearly-mean value of variable is correlated with month
and then hourly to the monthly-mean value is correlated with day-hour
s. On comparison of the computed results with the measured data of the
remaining 5 cities, yearly-average relative standard deviations are 1
4.6, 10.5 and 26.7% for monthly-mean hourly relative humidity, ambient
temperature and wind velocities, respectively. (C) 1998 Elsevier Scie
