Description: Special Report
Introduction: During mid and late summer, a shallow advection fog frequently forms over the open water of North Star Bay just north of Thule Air Base, Greenland. Light northerly winds, 4-6 knots, move this fog inland between North and South mountains over Thule AB. Occasionally the fog dissipates as it progresses in land over the runways due to radiational heating of the land. During these periods, one end of the field is operating under Visual Flight Rules for light aircraft and helicopters, but the field is closed for larger aircraft which must make their approach from the sea. It is not uncommon for incoming air traffic to be halted for as long as a week or more. This situation is particularly troublesome because it occurs at times when air transportation is needed most; i.e. , when major research projects are being activated and personnel replacement and area resupply are being completed before the long arctic night sets in. The need for keeping this base open for air traffic is therefore great.
