Mesoscale meteorology is the study of weather systems and processes at horizontal scales of approximately 5 kilometres (3 mi) to several hundred kilometres. It is smaller than synoptic-scale systems (1,000 km or larger) but larger than microscale (less than 1 km).

Mesoscale Motions. Static stability and its spatial variations may produce complex mesoscale motions. Since wind speeds and the frequencies of weather systems are strongly subsonic, it follows that the pressure fields are in a state of ‘anelastic’ balance with the temperature and velocity patterns.

2019年3月30日 · Weather phenomena that are small in size—too small to be shown on a weather map—are referred to as mesoscale. Mesoscale events range from a few kilometers to several hundred kilometers in size. They last a day or less, and impact areas on a regional and local scale and include events such as:

2024年9月16日 · This study is focused on the development of mesoscale AMV (MAMV) products, which are distinguished by their exceptional quality and spatiotemporal resolution, leveraging data from the geostationary high-speed imager aboard the Fengyun-4B geostationary meteorological satellite (FY-4B/GHI).

What is “Mesoscale”? • Meaning is: “middle scale” or “in-between” scale • Synoptic – Mesoscale – Convective scale • Division of scales is not rigid – there is a continuum so that any phenomena is affected by other scales. For example, convective elements organized into a mesoscale system have both important convective

1992年3月1日 · Meso-scale circulations are responsible for weather events such as sea breeze, thunderstorms, lee-waves, severe downslope windstorms, polar lows and tropical cyclones.

It contains the features and equation set of mesoscale atmospheric motions, the topographically forced mesoscale circulations, the gravity waves in free atmosphere, the front and jet stream, the mesoscale convective systems (MCSs), the atmospheric instability, the factors effecting the development of MCSs, mesoscale weather diagnosis and ...

2004年1月1日 · Mesoscale dynamics includes the study of motion systems that have horizontal scales in the range of about 10 to 1,000 km. It includes circulations ranging from thunderstorms and internal gravity waves at the small end of the scale to fronts and hurricanes at the large end.

2023年3月21日 · While the “core” of the mesoscale is the meso-\(\beta\), which has the typical features of the mesoscale motions, while the meso-α and meso-γ are the transition between mesoscale and large scale or between mesoscale and small scale respectively and they may have both the features of large scale and mesoscale or mesoscale and small scale ...

Curved ow imbalances result in centripetal acceleration such that ow is approximately parallel to curved isobars, i.e. the gradient wind balance. Compared with synoptic scale disturbances (e.g., extratropical cyclones), mesoscale phenomena are more short-lived. The mesoscale Lagrangian timescales are bound by:
