Case: 05 April 2018

Summary

Precipitating open cellular event with strong (40-50 kt) westerly boundary layer winds

Description

An open cell event that followed a significant frontal passage. Several deeper precipitating cumulus were observed across the larger Azores model domain. Cloud tops were consistently approaching 4 km AGL from available observations. Strong westerly to northwesterly boundary layer winds (40-50 kts) were observed throughout this event. The melting level was around 1.5 km AGL, well below the cloud top heights as estimated by ARM profiling sensors.

Available assets
