Contrasting responses of urban and rural surface energy budgets to heat waves explain synergies between urban heat islands and heat waves
TL;DR: In this paper, the authors analyzed observations from two flux towers in Beijing, China and revealed significant differences between the responses of urban and rural (cropland) ecosystems to heat waves, implying synergies between HWs and UHIs.

Observations of wind speed profiles over Greater London, UK, using a Doppler lidar
TL;DR: In this paper, the authors presented wind speed profile data obtained from a Doppler lidar in central London, UK, during an 8 month observation period, used in conjunction with wind speed data measured at a nearby airport, to assess the accuracy of the predictions made by wind engineering tools currently available.

Evaluation of Urban Local-Scale Aerodynamic Parameters: Implications for the Vertical Profile of Wind Speed and for Source Areas
Christoph W. Kent,Sue Grimmond,Janet F. Barlow,David Gatey,Simone Kotthaus,Fredrik Lindberg,Christos Halios +6 more
TL;DR: Nine methods to determine local-scale aerodynamic roughness length and zero-plane displacement are compared at three sites in London, UK, indicating Morphometric methods that incorporate roughness-element height variability agree better with anemometric methods, indicating zd is consistently greater than the local mean building height.

Aerodynamic Properties of Urban Areas Derived from Analysis of Surface Form
C. S. B. Grimmond,Timothy R. Oke +1 more
TL;DR: In this paper, several methods to determine the aerodynamic characteristics of a site through analysis of its surface form (morphometry) are considered in relation to cities, including zero-plane displacement length (zd), roughness length(z0), depth of the roughness sublayer, and aerodynamic conductance.

Progress in the Statistical Theory of Turbulence
TL;DR: In this article, the similarity principle is applied to the problem of statistical mean values in the case of homologous turbulence, which is a generalization of the notion of velocity distribution in shear motion.
