Laboratory experiments indicate that an advancing ejecta curtain displaces the atmosphere and creates strong winds that entrain large amounts of fine-grained ejecta. A theoretical model describing the interaction between an atmosphere and the outward moving ejecta curtain allows one to estimate the magnitude and velocity of the winds in the induced ring vortex in order to establish the importan...

Although numerical models are essential to hurricane forecasting, many other applications require only statistical depiction of the wind distribution. In Holland’s 1980 parametric profile, radius of maximum wind, maximum wind, and a measure of the profile width describe the radial variation of the axisymmetric wind. Variants of the Holland profile are used to predict insurance underwriting risk...

Abstract We examined the climatological features of strong winds associated with extratropical cyclones around Japan during 40 seasons between November and April from 1979/80 to 2018/19 using reanalysis data. Our assessments revealed that caused most (80%–90%). Notably, contribution explosively developing is larger (70%–80%). The are mainly related warm conveyor belt (WCB) cold (CCB) inside exp...
