This wind comes to us from the industrial areas of the Ruhr, which has large amounts of pollutants trapped in under the temperature inversion. |
A temperature inversion is formed on still frosty nights and traps the emissions in a layer close to ground level. |
Under synoptic conditions favorable for migration, broadfront movements of migrants toward the south passed over the mountains, often above a temperature inversion. |
A temperature inversion would result at the top of the shallow layer, trapping any pollutants emitted into that layer. |
A temperature inversion is enough to prevent the kind of mixing that is needed to overcome ground drag and transfer the momentum of winds aloft down to the surface. |
Wet air flowing up from the Gulf rose above freezing air to the north forming a temperature inversion above the town. |
