A new, satellite-based methodology is developed to evaluate convective mass flux and large-scale total mass flux. To derive the convective mass flux, candidate profiles of in-cloud vertical velocity are first constructed with a simple plume model under the constraint of ambient sounding and then narrowed down to the solution that matches satellite-derived cloud top buoyancy. Meanwhile, the larg...

This study introduced real life application of first order differential equation. In this paper We basically discussed about different types equation and the solution in field science technology. Further, Newton’s law cooling orthogonal trajectory has been incorporated. Study convective boundary condition it is used for increasing temperature.

Impulsive and convective frequencies are one of the most important subjects for evaluation of the seismic behavior of tanks. These two frequencies are defined by Housner and used for obtaining Rayleigh damping in time history analysis. ACI 350 and NZSEE standards have suggested some analytical solutions for finding convective and impulsive frequencies. These frequencies can also extract from mo...

In this work we present a high-accurate discretization to solve the compressible Navier-Stokes equations using an Arbitrary Lagrangian-Eulerian meshless method (SPH-MLS), which can be seen as general formulation that includes some well-known meshfree methods particular case. The is based on use of Moving Least Squares (MLS) approximants weight functions Galerkin and accurate discretize convecti...

This paper studies the asymptotic stability of global solutions three-dimensional nonisentropic compressible Navier–Stokes equations, where initial data satisfy “well-prepared” conditions, and velocity field temperature Dirichlet boundary condition convective condition, respectively, based on incompressible limit solutions. With uniform estimates with respect to both Mach number <math xmlns="ht...

[1] We investigate the hypothesis that the 10 km diameter dome-shaped features seen on Europa’s surface are caused by strongly temperature-dependent convection, in which upwellings form isolated diapirs or thermals. We use the observed lower limit on dome diameter of 4 km to deduce that the conductive (stagnant) lid thickness must be 5 km. Such a lid thickness implies a minimum surface heat flu...

The present study has used Meteosat infrared brightness temperature images to investigate the regional and interannual variability of Central African cloudiness. Spatial and temporal variability were investigated using half–hourly data from the Meteosat-7 during June–July–August (JJA) of 1998–2002. The full domain of study (1.5◦E–17◦E, 1◦N–15◦N) was divided into six regions and statistics in ea...

[1] Quasi‐equilibrium (QE) closure is an approximation that is expected to apply to a large ensemble of clouds under slowly changing weather conditions. It breaks down under rapidly changing conditions or when the domain size is too small to provide an adequate sample of the cloud field. We explore fluctuations about an equilibrium state as simulated by a three‐dimensional cloud‐resolving model...

1. introduction thunderstorms or lightning storms are kinds of storms that generally are associated with the convective clouds and usually are resulted in hailing, strong winds, and flash floods. clouds of convective storms are observed in most regions, but a small percentage of the convective storms can produce severe weather conditions and flash floods that cause damages. a flash flood is a d...

An understanding of convective weather impacts on en route airspace capacity is a first step toward development of predictive tools to support both tactical and strategic routing decisions in storm-impacted airspace. This study presents a model for traffic reductions in en route sectors that result from convective weather impacts. A model to predict the impact of convective weather on en route ...
