Scatter plot of monthly averages of the daily soiling rate measured in Arica, Iquique, Calama, Copiapo, La Serena and Santiago, and the corresponding: (a) monthly wind speed averages; (b) monthly relative humidity averages.
The humidity averages in the 60% to 70% range year round becoming more noticeable on warmer summer days than in the cooler winter months.
Humidity averages 70percentt year-round.
**Annual mean value (driest monthly relative humidity average to most humid monthly relative humidity average).
The temperature hovered around 90 degrees, with relative humidity averaging 77.5percentt.
In Houston, Texas, the temperature on a typical July day reaches 93 °F (34 °C), with relative humidity averaging near 75percentt, but Minneapolis, Minnesota, more than 1,000 miles (1,600 km) north, is only slightly cooler and less humid.
The average air temperature, average wind speed, average humidity, average rainfall and average daily evaporation are presented in Table 2.
This includes readings of average sunlight, temperature, discomfort from heat and humidity, relative humidity, average Precipitation, and wet days.
Amplitude factors are correlated to steady-state operating data (temperature, humidity, average current, resistance, and voltage).
Site condition factors considered in the study were average air temperature, low air temperature, high air temperature, daily temperature range, relative humidity, average wind velocity, and evaporation.
They took into account weather information variables including temperature average, relative humidity average, wind speed average and information of previous electricity consumption as their model's input and found that the combined model improves the prediction of electrical load [14].
