Abstract. A stochastic deep convection parameterization is implemented into the US Department of Energy (DOE) Exascale Earth System Model (E3SM) Atmosphere version 1.0 (EAMv1). This study evaluates its performance in simulating precipitation. Compared to default model, probability distribution function (PDF) rainfall intensity new simulation greatly improved. The well-known problem “too much li...

Southeast Texas houses a precipitation transition zone between drier conditions to the North and West and some of the wettest parts of the continental U.S. to the East. The Region has seen an increase in its reported normal annual precipitation totals in recent decades. In order to determine if the additional rainfall has been influenced by warming temperatures or is within the variability of t...

As the planet warms, climate models predict that rain will become heavier but less frequent, and that the circulation will weaken. Here, two heuristic models relating moisture, vertical velocity, and rainfall distributions are developed, one in which the distribution of vertical velocity is prescribed and another in which it is predicted. These models are used to explore the response to warming...

The cloud feedback problem is one of the largest uncertainties in climate studies because cloud formation and dissipation are complicated processes. Clouds have mutual relations to aerosols and precipitation. Increases in aerosol concentrations result in a decreased drop size and modify the cloud radiative forcing. Decreased drop size may also suppress precipitation. Precipitation is generated ...

Climate change projections for California indicate reduction in the percentage of precipitation that falls as snow, and increase in the percentage that falls as rain, due to warmer temperatures in the future. Previous work has shown overall decreases in rainfall / snowfall ratios for the western US over the last 60 years. Of interest in this study is the quantification of snow/rain ratios for s...

We perform a complete analysis of the supersymmetric particle spectrum in the Minimal Supergravity (mSUGRA) model. We show that present constraints on the Higgs boson and superparticle masses from collider searches and precision measurements still allow for large regions of the mSUGRA parameter space where some sparticles as well as the heavier Higgs particles, are light enough to be produced a...

The broadband fixed wireless access (BFWA) systems operate in microwave frequencies. In this frequency range, the wave propagation is highly influenced by precipitation caused especially by rain. With the use of cell site diversity (CSD), the rain attenuation effects can be mitigated. When the signal level falls below a certain threshold the subscriber station switches to another base station w...
