A Brief History of the Geophysical Turbulence Program at NCAR
The history of the turbulence research at NCAR is divided in three periods and discussed. The periods are: 1960-1972, 1972-1984, and 1984 to the present.
Persistent Anomalies, Blocking and Predictability
The rotating annulus experiments presented in the last chapter reproduce some important qualitative features of the atmosphere’s highly complex general circulation. Sequences of daily weather charts show large-scale wave-like patterns retrogressing with respect to a westerly mean zonal flow. These traveling planetary waves have many similarities with the corresponding Rossby wave regime in a rotating annulus. The atmospheric traveling waves, however, are much less regular than the laboratory waves. They are superimposed, moreover, on standing waves forced by zonal asymmetries of the Earth’s surface, as discussed toward the end of Section 4.4, and in Section 4.6.
INTERNAL TIDES, SOLITARY WAVES AND BORES IN SHALLOW SEAS
Remote sensing and in situ observations of internal tides, solitary waves and bores in shallow water are briefly reviewed in this paper. The emphasis is laid on interpreting SAR images based on oceanographic measurements, and analyzing characteristics of internal waves in the China Seas. Directions for future research are discussed.
