A silver poplar in the north-west corner
of the Railway Field at South Farm,
Norton Bavant.
A sudden increase in humidity,
usually preceding a storm,
often causes the leaves of poplar trees
(and maples too) to turn their
silvery-colour backs upwards in the wind,
a good indicator that heavy rain is imminent.
The flipping upward of the backs of the leaves
happens when the humidity
causes limpness of the soft stems.
