Abstract: The hydrodynamic instability characteristics of planetary zonal flows are investigated through use of a quasi-geostrophic numerical model of high spatial resolution. An initial-value technique is employed to obtain solutions ...

Abstract: The numerical model of Part I is used in certain experiments designed to reveal special instability effects caused by the vertical walls which specify the lateral boundary conditions at the northern and southern boundaries ...

Abstract: Matrix elements ?0J|Q|v? J?? of the quadrupole moment Q connecting the vibrational level v = 0 of the ground electronic states of H2, HD and D2 to all the discrete vibrational levels v? are presented for the 0, Q and S ...

Abstract: Data from eight water vapor soundings made with the dew-point hygrometer instrument at McMurdo Sound, Antarctica, are presented. These data are compared with various north temperate latitude data. The soundings are too ...

Abstract: In an attempt to determine the relative contribution of the direct incorporation of cold air (detrainment from overshooting convective cloud tops) to the production of mesohighs in the vicinity of the tropopause, two ...

Abstract: A hybrid density function is given for describing wind-speed distributions having nonzero probability of ?calm.? A Weibull probability graph paper designed specifically for plotting wind-speed distributions is used to ...

Abstract: The temporal variation of specific humidity during morning hours was evaluated by analytic and numerical model scaling as well as by observational means. The scaling quantified (i) the gradual increase in the shelter ...

Abstract: Vertical velocities were observed during the month of June 1990 with two side-by-side wind profilers at Platteville, Colorado. Many of the observations reveal strong wave motion, probably mountain lee waves, that sometimes ...

Abstract: On the afternoon of 3 June 1981 a severe thunderstorm spawned two tornadoes which moved across a portion of metropolitan Denver. The tornadoes were classified as strong F2 intensity, and caused damage totaling over $1 5 ...

Abstract: This paper presents a comparison of two conventional detiding techniques carried out for ship-mounted acoustic Doppler current profiler (ADCP) data collected in the European shelf area of the Celtic Sea during the summer ...
