SUMMARY:Modelling entrainment and surface processes in atmospheric flows o
 ver rural and urban boundary layers. - Maarten van Reeuwijk\, Imperial Col
 lege London

CONTACT:Catherine Pearson
DESCRIPTION:In this talk I will discuss the influence of inner layer proce
 sses on the entrainment in an idealised night-time atmospheric boundary la
 yer (Jonker et al.\; 2013) by extending the entrainment decomposition meth
 od of Van Reeuwijk and Craske (2015) to wall-bounded flows. I will then di
 scuss the interaction between an urban environment and the overlying atmos
 phere\, particularly focusing on the effect of vegetation on the local urb
 an microclimate. It turns out that the temperature reduction and the evapo
 rative flux are linearly related\, and we explain theoretically why this i
 s the case.
