Meso-scale Networks of Surface Observing Stations
shown in figure A1 consists of 47 surface recording stations extending
from Norman, Okla., southwestward about 100 statute miles. Stations are
spaced 10 to 15 mi. apart and continuously record pressure, temperature,
relative humidity, precipitation, and wind speed and direction. Plans
exist for instrumenting a 1500' television tower near Oklahoma City, and
installing new stations along the north side of the present establishment.
Network data are further augmented by rawinsonde ascents made serially
at Fort Sill, at Will Rogers FieId, and at Tinker Air Force Base, aIso
shown in this figure. Other surface weather observations are available
from Ardmore, Hobart, Clinton-Sherman AFB, Fort Sill, and Wichita Falls,
Tex. Reports on severe weather are received from about 400 volunteer observers
in the area who are supplied special reporting forms by NSSL.
A2 shows the network of 173 recording rain gages operated all year
by the Agricultural Research Service of the Department of Agriculture.
These gages are spread over 1100 mi.2 of the Washita River
Watershed, where 12 stream gages are also operated. The 3-mi. spacing
of the rain gages yields data only slightly coarser than the resolution
of the radar.
