Abstract The impact of land variables on temperature forecasts in atmospheric cycling is often underestimated or overlooked. This oversight primarily occurs due to the abundance of meteorological measurements available for assimilation and partly bec

Hailstones have large damage potential; however, their explicit prediction remains quite challenging. The uncertainty in a model’s initial condition and microphysics are two of the significant contributors to the challenge. This two-part study aims
