Heat Stress

As in humans, heat stress can cause many adverse effects to exposed crops by reducing yield or causing total crop failure.  Plant heat stress is defined as those time periods during which the canopy temperature exceeds the upper limit on the Thermal Kinetic Window (TKW).  Forecasts of plant heat stress can provide time for growers to use protective measures.


CFAN has developed a cotton heat stress forecast model for the Camilla region of Georgia.  A canopy temperature model is coupled with the ECMWF Ensemble Prediction System (EPS), which are used to generate medium range forecasts (10-day) as well as 24-hour forecasts of heat stress.
