We study convection and convective cloud patterns in order to understand how land-surface heterogeneity affects such patterns and how they can be parameterized. The large-eddy atmosphere and land-surface model (LES-ALM) will be further developed and run for surfaces with different heterogeneity scales. The model capability in reproducing convective clouds in response to land-surface processes will be tested against measurements. A scheme for cloud pattern parameterization will be developed and tested in a weather-prediction model for selected regions.

我们研究对流和对流云的模式，以了解如何陆面异质性影响这种模式，以及如何将它们参数化。将进一步发展大涡动大气和陆面模式（LES-ALM），并为不同非均匀尺度的陆面运行。将根据测量结果检验模式再现对流云对陆面过程的反应的能力。将为选定区域的天气预报模式制定和测试云型参数化计划。
