TLDR
In this article, a mesoscale wind field model was used to simulate a cyclonic nocturnal eddy which may form over Melbourne under stable conditions with light synoptic winds.Abstract:
A mesoscale wind field model is used to simulate a cyclonic nocturnal eddy which may form over Melbourne under stable conditions with light synoptic winds. Two types of eddy (Mel-I and Mel-II) are identified, with separate formation mechanisms. Mel-I is generated by vorticity shed from the upstream mountain ranges. Daytime anabatic effects enhance the strength of the eddy. When surface heat fluxes are suppressed, the numerical simulations are found to parallel previous to laboratory experiments, but with a somewhat relaxed Froude number formation criterion. The second type of eddy, Mel-II, is generated by interaction of the sea breeze front with the synoptic flow. The eddies are compared with the Kanto plain eddy modeled by Kimura.read more

Observations and numerical modelling of Lake Ontario breezes
Neil T. Comer,Ian G. McKendry +1 more
TL;DR: In this article, two years of land-based data showed that the Lake Ontario breeze develops on 30% of the days during summer and typically develops in mid-morning and persists until the late evening when it is replaced by a well developed landbreeze regime.

Review: Mesoscale modelling in complex terrain
TL;DR: In this article, the authors focus on those aspects of mesoscale models which require special techniques and parameterizations when modelling flow over complex terrain, and the basic concepts and limitations of various approaches are discussed.
