Middle-Asia vortex (MAV)is an important influencing system which causes rainstorm, short-time heavy precipitation, hail and persistent low temperature events. The main study results on Middle-Asia vortex(MAV)are summarized in the last 50 years, which include MAV definition, time-space distribution, life cycle, activity regular pattern, influences on weather in Xinjiang, circulation configure, water vapor transportation, three-dimension dynamic and thermodynamic structure and physics causes of MAV. Some problems remaining to be resolved are pointed out as follows: the structure and developing regular pattern of meso-scale system underground MAV, physics models and meso-scale analysis diagnose physical quantity of strong convective weather, key influence factors and warning- forecasting index of strong convective weather causing by MAV. To solve the above-mentioned problems, it is very important for improving synoptic meteorology and short-term short-time forecast technology in Middle-Asia areas and enhancing the capability of disaster prevention and reduction.
