Observations from Space and Thermal Convection: A Historical Perspective
Publisher: American Meteorological Society
Abstract: An abbreviated historical account of the evolution of the satellite meteorology program is presented. Emphasis is placed on the importance of the satellite and its space platform for observing and studying atmospheric ...
Trends in Cyclone and Anticyclone Frequency and Comparison with Periods of Warming and Cooling over the Northern Hemisphere
Publisher: American Meteorological Society
Abstract: Available datasets and pertinent climatological studies have been examined to show the statistical trends in frequency of cyclone and anticyclone events for the Northern Hemisphere during periods of warming and cooling ...
An Artificially Induced Local Snowfall
Publisher: American Meteorological Society
Abstract: Observational evidence of a locally induced snowfall is presented. Local snow cover patterns are shown along with accompanying meteorological data which suggest that the precipitation process was initiated by the introduction ...
Some Inferences of Eddy Viscosity Associated with Instabilities in the Atmosphere
Publisher: American Meteorological Society
Abstract: Manifestations of both Rayleigh-Taylor instability and Kármán vortices in atmospheric flows are recognized, and existing theory is applied to infer some values for the horizontal and vertical eddy transport coefficients ...
Note on ITCZ Wave Disturbances and Formation of Tropical Storm Anna
Publisher: American Meteorological Society
Abstract: An examination of Applications Technology Satellite 3 photographs of the Atlantic intertropical convergence zone (ITCZ) for the period May through July of 1969 has revealed an excellent case of ITCZ wave instability that ...
Present Climatic Cooling and a Proposed Causative Mechanism
Publisher: American Meteorological Society
Abstract: Evidence has been presented and discussed to show a cooling trend over the Northern Hemisphere since around 1940, amounting to over 0.5°C, due primarily to cooling at mid- and high latitudes. Some regions of the middle ...
A Revised Tornado Definition and Changes in Tornado Taxonomy
Publisher: American Meteorological Society
Abstract: he tornado taxonomy presented by Agee and Jones is revised to account for the new definition of a tornado provided by the American Meteorological Society (AMS) in October 2013, resulting in the elimination of shear-driven ...
Further Aspects of Transitions in Two-Dimensional Thermal Convection
Publisher: American Meteorological Society
Abstract: In this paper we present the results of numerical investigation of a two-dimensional nonlinear set of Boussinesq equations governing Bénard?Rayleigh convection using spectral representation in the horizontal direction and ...
A Numerical Study of Atmospheric Convective Scaling
Publisher: American Meteorological Society
Abstract: The phenomenon of selective scaling in shallow atmospheric convection is examined with the use of a two-dimensional, fine-resolution numerical model with a large domain aspect ratio. No extra model physics (such as latent ...
Aircraft Investigation of Mesoscale Cellular Convection During AMTEX 75
Publisher: American Meteorological Society
Abstract: The 1 s data set collected by the NCAR Electra research aircraft in the presence of closed mesoscale cellular convection (MCC) has been examined for the purpose of determining the convective wind field and horizontal ...
