How a frost pocket sits in a yard
Cold air is denser than warm air, so on a still night it slides downhill and pools.
When the purchase is complete, return to the original window. It will refresh.
From the opening
A frost pocket is a low place where cold air collects on a clear, still night. Plants there can freeze while the same species a little way up the slope does not, because the cold air has drained to the bottom. The opening covers cold air drains downhill, clear still nights sort the yard, and fences can stop the flow.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
