Sea ice terminology, which describes an iceberg that has eroded in such a way that a U-shaped slot is formed near or at water level, with twin columns or pinnacles.
The freezing of the soil and terrestrial objects caused by a reduction of temperature when the adjacent air does not contain sufficient moisture for the formation of hoarfrost on exposed surfaces. Wit
h respect to vegetation alone, this is termed a black frost. A dry freeze is usually considered to be a more local and short-period (probably radiative) phenomenon than a freeze.
Solidified carbon dioxide that, at -78.5C and ambient pressure, changes directly to a gas as it absorbs heat. It is used as a coolant to induce the ice phase for supercooled cloud and fog modification
procedures.
A low-level mesoscale boundary or transition zone hundreds of kilometers in length and up to tens of kilometers in width separating dry air from moist air.
