| 摘 要： | 用一个β平面准地转正压模式，实施了5组时间积分为72个模式日的试验，分析了不同基本气流对局域流型演化特征的作用。结果指出:强的基本气流相应于持续性干旱流型；弱的基本气流相应于间歇性的干旱流型。

| Abstract: | By using a quasigeostrophic barotropic model, five experiments whose integration timesare 72 model days were Performed in order to study effects of various basic currents on evolutionalcharacteristics of local flow patterns which are responsible for the regional drought. Results show thatthe intense basic current corresponds to the formation of the continuous drought flow patterns, and theweak corresponds to the intermittent ones. |
