摘要
Influence of soil moisture and vegetation on persistence of short-term climate anomalies isanalyzed theoretically through a heat and water balance model in coupled air-land system.It is shown that the soil hydrologic condition, rather than the soil thermal situation, is adominant factor in maintenance of climatic anomalies. The persistence of climate anomaliesis dependent largely on the capacity of water and heat exchange on the land surface. The cli-mate anomalies would persist longer for less soil moisture or vegetation cover. Furthermore,compared with humid areas, the climate anomalies persist longer in an arid climate envi-ronment.
