Basic Concepts for Convection Parameterization in Weather Forecast and Climate Models: COST Action ES0905 Final Report

Basic Theory Behind Parameterizing Atmospheric Convection

Last fall, a network of the European Cooperation in Science and Technology (COST), called “Basic Concepts for Convection Parameterization in Weather Forecast and Climate Models” (COST Action ES0905; see http:// w3 .cost .esf .org/ index .php ?id =205 & action _ number =ES0905), organized a 10-day training course on atmospheric convection and its parameterization. The aim of the workshop, held o...

Description of Mixed-Phase Clouds in Weather Forecast and Climate Models

This project takes its cue from field experiments, mostly from the Arctic Summer Cloud Ocean Study (ASCOS), which was a summer expedition on the Swedish icebreaker Oden during the summer of 2008 as part of the International Polar Year, and a new expedition scheduled for the summer of 2014, also on the icebreaker Oden: the Arctic Cloud in Summer (or ACSE) experiment, which is a part of a larger ...

Adaptive Grids for Weather and Climate Models

An adaptive grid technique has been applied to a revised version of NCAR/NASA’s next generation dynamical core for climate and weather research. This hydrostatic so-called Lin-Rood dynamics package is based on a conservative and monotonic finite volume discretization in flux form. The adaptive model design utilizes a spherical adaptive-grid library which is based on a cache-efficient block-stru...
