周期性热力外强迫和地形强迫共同激发的六月和十月的流型突变
ABRUPT CHANGES OF FLOW PATTERNS IN ASIA DURING JUNE AND OCTOBER BY OROGRAPHY AND PERIODIC THERMAL FORCINGS
-
摘要: 本文用二层准地转模式,经低谱途径,数值地研究了周期性热力外强迫源和地形强迫源共同作用下斜压大气的流型突变问题。在一定的参数范围,季节转换期间的流型突变清楚地显示出来了,该突变恰好发生在摸式大气的6月和10月。Abstract: A two-level quasi-geostrophic low-order spectral model by both the orography and the periodic thermal forcings is used to study the changes of flow patterns.In certain parametric combinations,the phenomena of tho abrupt seasonal changes of flow patterns in June and October exhibit distinctly.
