摘要本文介绍了四种夏季积云对流的水和能量收支。预算是根据国家冰雹研究实验rawinsonde数据计算的。对流分类是基于雷达和降水资料。预算方程的推导是为了指出两个条款，涉及到快速的时间变化和大的水平梯度，有时发生在预算领域。弱，中等和降水类的对流产生明显的水和能源的来源，一般类似于其他预算研究的结果，根据海洋和/或热带数据。发展中的对流类的结果表明，云存储项必须包括在研究对流，是从弱到中等或降水迅速变化。
Abstract Water and energy budgets are presented for four broad classes of summertime cumulus convection. The budgets are calculated from National Hail Research Experiment rawinsonde data. The convection classifications are based on radar and precipitation data. A derivation of the budget equation is presented in order to point out two terms that are related to the rapid time changes and large horizontal gradients that sometimes occur over the budget area. Weak, moderate and precipitating classes of convection produced apparent sources of water and energy that are generally similar to the results of other budget studies based on oceanic and/or tropical data. The results for the developing class of convection demonstrate that a cloud storage term must be included when studying convection that is rapidly changing from weak to moderate or precipitating.
