The approximate center of the most consolidated portion of the arctic pack ice, near 83° or 84°N and 160°W. This term was falling into disuse until its reintroduction with reference to antarctic International Geophysical Year (IGY) activity.
Industry:Weather
A gas for which the potential energy of interaction between molecules is independent of their separation and hence is independent of gas volume. Thus, the internal energy of an ideal gas depends only on its temperature. To a very good approximation, atmospheric gases at normal terrestrial temperatures and pressures are ideal.

Industry:Weather
A wind that opposes the intended progress of an exposed, moving object, for example, rendering an airborne object's airspeed greater than its groundspeed; the opposite of a tailwind. This effect is particularly critical in air navigation; it is of interest to note that a wind direction may have no component opposing the intended course of an aircraft, but because of drift effects, may have a component opposing the aircraft's heading.
