Noah‐MP With the Generic Crop Growth Model Gecros in the WRF Model: Effects of Dynamic Crop Growth on Land‐Atmosphere Interaction

In this paper we coupled a crop growth model to the Weather Research and Forecast (WRF) with its land surface Noah-MP demonstrated influence of weather driven on land-atmosphere (L-A) feedback. An impact study was performed at convection permitting scale 3 km over Germany. While leaf area index (LAI) in control simulation same for all cropland grid cells, inclusion resulted heterogeneous development higher LAI stronger seasonality. For analyses L-A coupling, two-legged metric applied based soil moisture, latent heat flux convective available potential energy. Weak atmospheric coupling is enhanced by model, terrestrial determines regions The turns no feedback path into strong positive coupling. number non atmospherically controlled days between April August increased 10 15 more than 50% Our work shows that results reduction both cold bias warm biases thus improves metrics distributed added value monthly mean temperatures. confirms annual phenological croplands regional climate simulations mid-latitudes crucial due processes currently observed expected future change phases.
