The Shape of Large Tropospheric Clouds, or “Very Like a Whale”
Publisher: American Meteorological Society
Abstract: Lovejoy (1982) analyzed radar and satellite images of convective clouds and rainbands extending over an area range from 10 to 106 km2 and found the fractal cloud-perimeter dimension to equal 1.35, indicating the presence ...
A Similarity Theory of the Tropospheric Turbulence Energy Spectrum
Publisher: American Meteorological Society
Abstract: A three-range model is proposed for the energy spectrum of tropospheric turbulence in which the range-I spectrum is governed by the cascade of eddy enstrophy, that of range-II by the cascade of eddy kinetic energy, and ...
The Rise of Strongly Radioactive Plumes
Publisher: American Meteorological Society
Abstract: The presence of radioactive gases in a plume, such as could occur in the event of a nuclear reactor accident, leads to the addition of buoyancy to the plume at an approximately linear rate. Buoyancy might also be added to ...
Some Recent Long-Range Diffusion Observations
Publisher: American Meteorological Society
Abstract: Recent atmospheric cloud-spreading (relative diffusion) data from a variety of sources are combined to show that the horizontal spreading rate is approximately linear over a time range from 1 to 10 or more hours (20?200 ...
Tropospheric Relative Diffusion Observations
Publisher: American Meteorological Society
Abstract: Data on relative on relative atmospheric diffusion, that is, the spreading by diffusion of puffs or particle pairs (e.g., of balloons) relative to their mutual center of mass, are reexamined. Richardson (1926) proposed his ...
