We conducted a detailed examination of the temperatures of a tea bush throughout the night of severe frost. The temperature was measured at various heights and distances from the frost fans. The surface temperature of a tea bush decrease to -4°C . There little difference between the air temperature at the height of the frost fan motor and the surface temperature of a tea bush.
