“…Evidence for this mechanism is seen in the latitudinal structure of the ozone tendency correlations, which are out-of-phase between the tropics and high latitudes (reflecting the overturning Brewer-Dobson circulation). This global-scale latitudinal see-saw is also apparent in stratospheric temperature changes during planetary wave events (first noted in satellite observations by Fritz and Soules 1972), and first documented in satellite ozone measurements in Randel (1993). Smith (1995) has accurately simulated these global stratospheric variations, using an idealized threedimensional model forced by transient tropospheric wave events.…”

Variability in planetary wave forcing from the troposphere to the stratosphere is reflected in changes in ozone transport, due to fluctuations in the stratospheric Brewer-Dobson circulation and eddy mixing. This work examines the space-time patterns of correlations between column ozone tendency and planetary wave Eliassen-Palm (EP) flux into the lower stratosphere, using monthly mean data for 1979-2000. Strong correlations are found during winter-spring in both hemispheres, with out-of-phase ozone changes between the tropics and middle-high latitudes. Springtime polar ozone is strongly influenced by wave forcing in both the Arctic and Antarctic. The ozone tendency-wave forcing correlations are combined with observed variations in EP flux to estimate the dynamic contribution to decadal-scale NH ozone trends. These calculations suggest that interannual changes in EP flux contribute @20-30% of the observed trends in column ozone over N during the past two decades.

“…Operational Soundings. In moving from the realm of experiment to an operational system, the remote sounding of the atmosphere from satellites has demonstrated the utility as well as the limitations of present day techniques (Fritz, et al, 1972). The current operational instrument, VTPR, has flown on the NOAA 2 and 3 satellites and will continue to serve as the operational sounder until its replacement by a third generation system, TOVS, in 1977.…”

“…This relationship was used in a .statistical modelling technique to describe global cloudiness. Koffler et al (1973) Radiances from Nimbus 3 SIRS show that winter polar stratospheric warmings are accompanied by relatively small stratospheric cooling in the tropics and summer hemisphere (Fritz and Soules 1972). Solar heating of the tropical stratosphere would produce large temperature gradients.…”

The year 1975 marks the fifteenth anniversary of the U.S. meteorological satellite program, which began on April 1, 1960, when the Tiros 1 experimental satellite was launched. Television pictures taken by the spinning Tiros 1, in a near‐earth, non–sun‐synchronous orbit, were often oblique and poorly illuminated. Nevertheless, they showed the organization of weather systems with a clarity never before seen and revealed phenomena that previously were unknown. Within a few days of the launch of Tiros 1 the new data were being used operationally to improve weather services [National Environment Satellite Service (NESS), 1971]. At the same time extensive research was carried out to increase our knowledge of the atmosphere and to develop techniques to utilize the new type of data.

“…Fritz and Soules (1972) showed a synoptic distribution of radiance from the channel 8 of SIRS on Nimbus 3, which is considered to be representative of the temperature in the middle stratosphere. Inspection of their synoptic charts reveals that planetary-scale waves of wavenumber 1 to 3 are dominant in middle latitudes of the Southern As a background analysis of the summer stratosphere and mesosphere, Fig.…”

An analysis was made of planetary-scale variations of temperature and wind fields in the summertime stratosphere and mesosphere by the use of meteorological rocket and satellite observations.From the vertical time-section analysis of temperature and wind at Cape Kennedy (28N, 81W) and other rocket stations in subtropics of the Northern Hemisphere, it is found that the oscillation with a period of about 15 days is predominant above 30 km.To describe the nature of wind and temperature oscillation in more detail, a power spectral analysis was made of the time series rocket data during the period of three months from July to September in 1969 and 1970. The result suggests that the oscillation as revealed by the analysis for indivisual observation station is a reflection of the horizontal movement of planetary-scale wave disturbances embedded in the mesospheric easterlies.The presence of traveling planetary waves in the summertime stratosphere was confirmed by means of a zonal harmonic analysis of ITOS-D VTPR retrieval data and Nimbus-5 SCR radiance data for the Southern Hemisphere in 1972/1973 summer, and the wavenumber-frequency relation is given in a quantitative manner.
