Observations of the development of convection through a series of stable layers during the Convective Storm Initiation Project

Abstract: This article describes the development of convection through a series of stable layers on 20 July 2004 during the pilot project of the Convective Storm Initiation Project (CSIP). Convective clouds developed in south central England as a result of diurnal heating. They formed near the south coast and grew gradually as they moved northwards, eventually producing light precipitation. Several stable layers and associated dry layers (or lids) were observed by sequential radiosondes launched every two hours. Most of… Show more

“…The delaying or weakening of deep convection due to atmospheric lids, regions of high CIN, and also their impact on the transition from shallow to deep convection has been shown in several previous studies (e.g. Morcrette et al, 2007;Bennett et al, 2008). Here, similar to these studies, a billow of increased static stability over the leeward slopes hinders the formation of strong convection.…”

“…The dry layers then moved eastwards over the UK behind a cold front and ahead of and partially beneath an upper-level PV anomaly. Whilst these CSIP cases investigated the links between the upper-level PV anomaly and the capping layers beneath them in some depth, there are other examples in the literature of such layers in the vicinity of PV anomalies and convection, such as Browning and Hill (1985), Griffiths et al (1998), Browning and Roberts (1999), Reid and Vaughan (2004) and Bennett et al (2008). No similar cases have been reported for continental Europe.…”
