TL;DR: In this paper, a satellite-based approach was proposed to extract 3D urban morphology information, and then retrieve and validate typical urban morphological parameters for urban climatic applications, such as building coverage ratio (BCR), building height (BH), building volume density (BVD), frontal area index (FAI), sky view factor (SVF), and roughness length (RL), to generate a Hong Kong Urban Climatic Map.

TL;DR: In this article, the synoptic-scale characteristics of these heat waves and associated atmospheric circulation anomalies are investigated, and the authors examine three summers with intense and protracted heat waves: the summers of 2003, 2006, and 2013, with high temperatures located mainly in southeastern, southwestern, and eastern China, respectively.

TL;DR: In this paper, the authors defined HTEs as days with daily maximum temperature above the 90th percentile derived from a specific climatological period and investigated two key domains in the upper level that are associated with HTE variation, the exit and the tail of the East Asian Jet Stream (EAJS), are identified.

TL;DR: In this paper, the authors investigated summer high temperature extremes (HTEs) in southeast China and their linkage with the El Nino-Southem Oscillation (ENSO) and atmospheric circulations in the East Asian summer monsoon (EASM).

TL;DR: In this article, the authors apply the extreme value theory to model and detect trends in extreme UHI events in Hong Kong, which have rarely been documented, and find that the risk of mortality and heat related diseases due to heat stress at night (when the daily maximum UHI occurs) in summer is also increasing.
