How Trees Change Urban Comfort

The most immediate physical effect of street trees, according to the speaker, was the they cast across the road surface, blocking direct sunlight.

The research compared air temperature with the heat that had built up in the once sunlight had dropped lower in the sky.

Air circulation behaves very differently in tightly enclosed rows of tall buildings, a formation the speaker calls , compared with open public squares.

A few particularly exposed junctions behaved like natural , which made the measurements less predictable.

Once darkness fell, the team predicted that cooler air movement described as would have more influence on temperature than patterns observed during the day.

The finding that surprised the team most was an improvement in residents' in streets where tree cover had reduced the amount of stored heat.

The team recommended prioritising the installation of in areas where residents were already accustomed to spending time outside.

Residents commonly reported what the speaker describes as a on entering streets where temperatures had been lowered by planting.

Professor Marlowe concludes that the impact of street trees extends beyond heat reduction to the broader quality of across the city.
