Weather Effects Landscapes
need water at changing rates based on weather conditions. Water leaves plants and soil through evaporation.
weather has a direct effect on evaporation, changing weather condition have an effect on how often landscape watering is needed.
Evaporation Can Be Measured Based On Weather Conditions
Landscape, golf and agricultural water managers
have been using weather stations to measure the loss of soil moisture caused by evaporation for over 30 years.
Evaportranspiration, or ET, is a measurement
of water that evaporates into the air from the soil and the amount of water used (transpired) by a plant. ET is used to determine
how much water must be returned to the soil, either by rain
fall or by using a sprinkler system. ET is typically expressed in hundredths of inches of water per day. ET losses are calculated
using meteorological data measured with a weather station. Weather parameters used to calculate ET include; solar energy,
air temperature, wind speed, humidity.
