摘要
江淮倒槽内常有边界层东南风急流出现,它的前方有中尺度的强降水。初生时,边界层东南风急流的中尺度特征比较明显。由于摩擦作用,沿江淮倒槽有锋生,它所强迫的次级环流,是边界层东南风急流的机制。
The boundary layer SE wind jet often appears in the Jianghuai invert trbugh and there was mesoscale precip tation in the front of it. The mesoscale characters of the boundary layer SE wind jet are clearer in the early part of jet formation. Under the action of friction, there is frontogenesis along the Jianghuai invert trough, The secondary circulation forced by fronfogenesis is the mechanism of the boundary layer SE wind jet.
