Radiances obtained from the 11-μ window channel by MRIR scanning
radiometer of NIMBUS II were investigated in order to determine areas
of time change of T₂, which may be related to effective cloud top level
of the five-day mean cloud state. A statistical model was developed
that is useful in obtaining a valid specification for effective cloud
top change, using a stepwise regression program.
The parameters ΔT₁, ΔZ, and T₂
appear to provide the necessary
spatial and temporal stability to employ the specification scheme over
a time span of ten days. These three parameters are all highly descriptive
of ΔT₂

in terms of basic atmospheric dynamical relationships. It
is recommended that a test be made of this hypothesis using a 24-hour
specification procedure.
