中文摘要:
      七十年代,谢义炳教授指出:湿大气动力学和干大气动力学特征有明显差异.结合我们的天气实践,注意到经常造成鄂北强降水的西南低涡处于对流层低层,在这一层次内不仅流场辐合明显,而且水汽丰沛,空气为强烈的对流性不稳定,这些因子对低涡的生消移动必然有较大的影响.
英文摘要:
      In this paper,the simplified vorticity equation is applied to moist baroclinic atmosphere.Considering the horizontal variation of the wet static stability and assuming a sine wave variation of vertical velocity with height,solutions of vertical velocity and vorticity tendency are obtained.Using this vorticity tendency equation,the dominant factors and the forecasting of the developing and east-moving lower troposphere vortex bringing heavy rainfall are discussed.
