Cloud Microphysics and the Tropical Climate: Cloud-Resolving Model Perspective

Atmospheric Electricity and Cloud Microphysics

The terrestrial atmospheric electrical system covers a range of dimensional scales, from charged molecular clusters to convective cloud systems. Charge-exchange associated with thunderclouds leads to positive charge in the upper conductive regions of the atmosphere and a net negative charge on the planetary surface. In non-thunderstorm regions, a vertical ionic current flows, replenishing the a...

Cloud microphysics and aerosol indirect effects in the global climate model ECHAM5-HAM

The double-moment cloud microphysics scheme from ECHAM4 that predicts both the mass mixing ratios and number concentrations of cloud droplets and ice crystals has been coupled to the size-resolved aerosol scheme ECHAM5HAM. ECHAM5-HAM predicts the aerosol mass, number concentrations and mixing state. The simulated liquid, ice and total water content and the cloud droplet and ice crystal number c...

Convective Cloud Distribution in a Cloud Resolving Model

Ground-Based Cirrus Observation in the Japanese Cloud and Climate Study: A Sonde System for Radiation and Cloud Microphysics Measurement

Clouds play a crucial role in radiative energy budget and water cycle in the earth-atmosphere system. In order to understand processes such as global warming and to improve assessment of climate change, it is necessary to develop climate models which properly take into account radiation and cloud processes. In addition, it is also important to improve satellite monitoring systems for measuring ...

Cloud Tracking in Cloud-Resolving Models

In recent years Cloud Resolving Models (CRMs) have become an increasingly important tool for the study of convective phenomena. CRMs should not be regarded as simply providing surrogates for observations; rather, they allow idealized but realistic simulations to be produced which provide a laboratory for the careful diagnostic analysis of generic convective systems. Such analysis is a distincti...
