Analysis of nocturnal urban heat advection using crowd weather stations

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 773, October 2025 Part B.
The urban heat island is often studied under calm conditions, where its development is strongest. However, effects of wind speed and direction need to be considered for a full understanding. We study the effects of urban heat advection in the urban canopy layer using crowd weather stations. Wind causes increased exposure to urban heat for areas located
