A Numerical Model to Investigate Optimum Liquid Carbon Dioxide Seeding Rate in Weather Modification Projects

A Numerical Study of Sensitivity of the Physical Dissipative Technique to Precipitation Parameterization in a Mesoscale Model

In this paper the numerical comparative experiments on sensitivity of the physical dissipative technique to the precipitation parameterizations, especially the different combination of the explicit micro-physical schemes and cumulus convection parameterizations, in the PSU/NCAR mesoscale model MM5V3 with a triple-nested domain are conducted using the case of heavy rain occurring in the northern...

Autoconversion rate bias in stratiform boundary layer cloud parameterizations

Because of their large grid-box size, global climate models do not explicitly represent small-scale processes occurring in cloud systems in the marine boundary layer. One such process, which is thought to have an important climatological effect, is the production of warm rain. Parameterizations of this process typically partition the liquid water into a cloud and a rain component. The rate of c...

a study on rate making and required reserves determination in reinsurance market: a simulation

reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
