Is land surface processes representation a possible weak link in current Regional Climate Models?

Representation of land-surface processes in aeolian transport models

Mathematical modelling provides an essential tool for understanding aeolian transport of dust and sand, its spatial and temporal dynamics, and its role in the earth system. As much of the crucial action takes place at or just above land surfaces, adequate representation of land-surface processes is essential. In this paper, we review progress in aeolian transport modelling during last two decad...

Link between land-ocean warming contrast and surface relative humidities in simulations with coupled climate models

[1] Simulations of warming climates with coupled climate models exhibit strong land-ocean contrasts in changes in surface temperature and relative humidity, but little land-ocean contrast in changes in equivalent potential temperature. A theory that assumes equal changes in equivalent potential temperature over land and ocean captures the simulated land-ocean warming contrast in the tropics if ...

Land-Use/Convection/Regional Climate

This paper reviews the cumulative effect of land-cover change on local, regional, and global weather and climate. Documented land-cover changes from 1700 to the present are shown to be particularly significant in the tropics. Model results are presented which show the teleconnection of weather patterns worldwide result from these landscape changes.

Nikinmaa assessment of land - cover data for land - surface modelling in regional climate studies

We studied the land-cover data used by the regional climate model REMO and the land surface model JSBACH, for Finland and surrounding areas. To date, the land-cover data determining REMO’s surface parameterisations have originated from the Global Ecosystem classification of the Global Land Cover Characteristics (GLCC-GEC) database. The same database has also been used as basis for prescribed pl...
