The aggregation rate of ice crystals depends on their shape and intercrystal relative velocity. Unlike spherical particles, the nonspherical ones can have various orientations relative to the gravitational force in the vertical direction and can appr

A developing cumulus cloud (Cu) was modeled, and dynamic, thermodynamic and microphysical properties of an ascending head bubble reproducing the upper part of a developing Cu were investigated. The data for analysis is taken from 10-m resolution LES

A new, computationally efficient Semi-Lagrangian advection (SLA) scheme was used to simulate an idealized supercell storm using WRF coupled with Spectral (bin) Microphysics (SBM). SLA was developed to make complicated microphysical schemes more compu

We present a semi-analytical model for the dispersion of passive scalars from continuous ground sources up to distances of a few hundred metres. We attempt to cope with problems typical of analytical models, such as the correct representation of the

The present work deals with the stable orientation of oblate and prolate spheroids in general steady linear flows and with the mode of convergence to these stable orientations. The orientation dynamics is governed by the Jeffery equation. The stable

The dynamics of the orientations of prolate ellipsoids in general linear shear flow is considered. The motivation behind this work is to gain a better understanding of the motion and the orientation probability distribution of ice particles in clouds

Trajectories of inertial spheroidal particles moving in a shear flow near a solid wall are calculated numerically from the Stokes flow equations by computing the hydrodynamic forces and torques acting on the particles. Near the wall these interaction

Hydrodynamic forces and velocities of spheroidal particles in a simple shear flow near a solid wall are calculated by a variant of the boundary integral equation method, combined with the use of the reciprocal theorem for Stokes flow equations. It is

In this paper a method of optimal interpolation of the vector field is suggested. It is shown that the vector estimator and its associated error are independent of the choice of the coordinate system in which to represent the wind. The use of the met
