For a three-dimensional, time-dependent thermal plume in stably stratified ambient above a heated square plate, formulations, numerical methodology, and computed results were shown. The temperature field was three-dimensional and extremely complex, and was elucidated as follows: An easing lump (EL) and a large strength of cross-over (CO) were discovered and characterized the temperature field in the plume above a heated square plate. The EL was formed above the temper ature front in order to transfer upwards a large quantity of heat from the front, ease the temperature decrease, and increase upwards the temperature. The CO region was composed of the near-front region, EL, and the above-EL region where the temperature is higher than that in the ambient on the given height, and had an extremely large strength of CO. The temperature field at the strong stratification was time-dependent and differed clearly from that at the middle stratification with steady state.
