Trees = cold air

[Alan Sibbald, Land Use Division]

My colleagues and I have made measurements of temperature *below* the canopies
of widely-spaced trees in the UK. The effect of the trees is to buffer
temperature; maxima (in the daytime) are lower and minima (at night) are higher
than in the open.

Perhaps you would have felt an *increase* in temperature if you had driven in
your convertible close to the trees at night. Driving in a convertible at night
in the UK is not, however, generally recommended so I haven't tried it.
