Depending upon the intensity of near surface temperature gradients, following two criteria are considered in terms of temperature at 2 meters ([T.sub.2]), surface temperature ([T.sub.surf]), and dew-point depression temperature ([T.sub.Dep]) subject to satisfying (1) and (2) above.
And the dew-point depression temperature is less than 8[degrees]C.
