Modelling study of Mesoscale Cyclogenesis over Ross Sea,Antarctica,on February 18,1988
This paper examines the development of a summer event of mesoscale cyclogenesis off the coast of Victoria Land in the presence of katabatic winds, by means of numerical simulations. These refer to the period from 00 UTC 17 February to 00 UTC 19 February 1988 and were performed using the hydrostatic...
