Reply to comments by David M. Schultz on 'Cloud-resolving model simulations of multiply-banded frontal clouds' (October A, 2005,131, 2617-2637)

摘要

The aim of Pizzamei et al. (2005) (P05 below) was to examine the interaction of upright and slantwise convection in a frontal zone using an idealized modelling environment. Triggering was found to occur on both the warm and cold sides of the frontal zone and was forced by a spreading cold pool due to evaporation in the slantwise downdraught. The initially upright plumes became tilted due to inertial adjustment (so-called AM adjustment) leading to multiply-banded clouds. Schultz (2006) (S06 below) assumes that in P05 we attempt to simulate the observed slantwise circulations of Browning et al. (2001) (B01 below) and he argues that we fail to do so. This is incorrect; we did not attempt to simulate in detail the circulations observed by B01. Nevertheless S06 raises some important issues regarding our modelling approach and we respond using the same section headings as S06 for ease of reference to his comments.
