We inves.igate the pos.ibility of cos.ic cens.rs.ip violation in the gravitational collaps. of radiating dyon s.lution. It is.s.own that the final outcome of the collaps. depends.s.ns.tively on the electric and magnetic charge parameters. The graphs.of the outer apparent horizon, inner Cauchy horizon for different values.of parameters.are drawn. It is.found that the electric and magnetic components.pus. the apparent horizon towards.the retarded time-coordinate axis. which in turn reduces.the radius.of the apparent horizon in Valdya s.acetime. Als., we extend the earlier work of Chamorro and Virbhadra [Pramana, J. Phys. 45 （1995） 181].

A s.x level regional primitive equation model has.been formulated and tes.ed for mons.on prediction. The model us.s.dynamic normal mode initialization s.heme for obtaining initial balance. The phys.cal proces.es.included are: the large s.ale condens.tion, the Kuo type of cumulus.convection, the s.rface friction, the s.ns.ble heat s.pply and evaporation over the s.a. The actual s.ooth orography is.included. The model has.been integrated for 48 hrs.us.ng input of 7 July and 8 Augus. 1979 when the domain of integration was.dominated by an intens. mons.on depres.ion. In order to inves.igate the model s.mulation of formative s.age of the depres.ion, the model was.als. integrated us.ng input of 4 July ***, the envelope orography has.been cons.ructed and included in the model for inves.igating its.effects.on the mons.on prediction.
