| Convection in a Nearly Isothermal Atmosphere. |

| Authors:
Albert Barcilon; FLORIDA STATE UNIV TALLAHASSEE
|
 | The onset of thermal convection is studied in a fluid layer having a basic density stratification that decreases almost exponentially with height. The coefficients of viscosity and thermal conductivity are assumed to be constant and a stratification parameter which measures the ratio of the depth of the fluid layer to the scale height is introduced. Critical Rayleigh numbers and wave-lengths are computed for various values of the stratification parameter. Finally, ... |

| ATMOSPHERIC PATH RADIANCE CALCULATIONS FOR A MODEL ATMOSPHERE, |

|
| The LITE-II Monte Carlo Program was used to calculate background radiances and path radiances as a function of altitude and direction for a model atmosphere illuminated by a broad beam monodirectional-monochromatic light source located at the top of the atmosphere. The model atmosphere has a ground level visibility of 25 km. LITE-II calculations were run for seven monochromatic plane light sources with wavelengths between 0.35 and 0.95 microns and angles ... |

| NEW MODEL ATMOSPHERES GIVING LATITUDINAL AND SEASONAL VARIATIONS IN THE THERMOSPHERE. |

K. S. W. Champion; F. A. Marcos; J. Slowey; AIR FORCE CAMBRIDGE RESEARCH LABS L G HANSCOM FIELD MASS
|
| A set of model atmospheres was prepared which constitutes a major advance in the representation of systematic variations in atmospheric properties between 120 and 250 km. The new models have three sets of boundary conditions at 120 km, which represent idealized variations with season and latitude, and connect with the new low altitude models which are a function of season and latitude. The three sets of high altitude models merge ... |

| THE EXPERIMENTAL MODIFICATION OF A BAROTROPIC NUMERICAL PREDICTION MODEL. |
JUN 1967 |
|
| Authors:
Howard Leo Lewit; NAVAL POSTGRADUATE SCHOOL MONTEREY CA
|
| There were two objectives in the experiments performed on the barotropic model. One was to correct the lag of the troughs and ridges noted in the barotropic model by the Naval Weather Research Facility, and the other was to introduce a baroclinic term. The approach to these problems was one which could be incorporated into the Fleet Numerical Weather Facility model with ease. Included herein are the theoretical development of ... |

| MEAN MONTHLY ATMOSPHERES FOR 15 DEGREES N. |

| Authors:

|
| The family of mean monthly atmospheric models presented in this report describe the vertical distribution of pressure, temperature, and density, at 15 degrees N, from the surface to 80 km. The models are internally consistent and are in agreement with observed winds, temperatures, and densities for the region between the equator and 30 degrees latitude. The amplitudes and phase angles of annual and semiannual oscillations in temperature and density at ... |

| SOME PROBLEMS OF NUMERICAL INTERPRETATION OF CLOUD INFORMATION FROM ARTIFICIAL EARTH SATELLITES. |
OCT 1966 |

| Authors:
Sh. A. Musaelyan; AMERICAN METEOROLOGICAL SOCIETY BOSTON MASS
|
| A previous article by the author gave a method for quantitative interpretation of cloud information from artificial earth satellites. Equations were given that may be taken as the relation between the Fourier coefficients of cloud and vertical motion fields for each latitude. Analysis of a large number of cloud charts showed that the large-scale cloud fields exhibit a certain conservatism, changing little from day to day, although the cloud cover ... |

| NUMERICAL STUDIES OF PLANETARY CIRCULATIONS IN A MODEL ATMOSPHERE. |

| Authors:
A. Huss; HEBREW UNIV JERUSALEM (ISRAEL) DEPT OF METEOROLOGY
|
| The evolution of general circulation patterns has been studied by means of a two-level quasi-geostrophic model incorporating diabatic heating and surface friction. An attempt was made to introduce water vapor into the model atmosphere, and to study the resulting patterns of evaporation and precipitation. (Author) |

| MEAN ATMOSPHERIC PROPERTIES IN THE RANGE 30 TO 300 KM. |

| Authors:
K. S. W. Champion; AIR FORCE CAMBRIDGE RESEARCH LABS L G HANSCOM FIELD MASS
|
| A planned COSPAR publication contains a set of atmospheres for several latitudes and times of year for the altitude region 30 to 80 km developed by G. V. Groves. A second set of atmospheres was developed by W. Priester and I. Harris ('The upper atmosphere in the range from 120 to 800 km,' Proposed CIRA, 1964) for the region between 120 and 800 km for various solar fluxes and times ... |

| STRATOSPHERIC ENERGY PROCESSES AND ASSOCIATED ATMOSPHERIC LONG-WAVE STRUCTURE IN WINTER. |

| Authors:
H. Stuart Muench; AIR FORCE CAMBRIDGE RESEARCH LABS L G HANSCOM FIELD MASS
|
| The question of the source of energy for the changes in the mid-winter stratosphere circulation pattern associated with the sudden warming phenomenon is examined. A set of energy equations is derived which is applicable to the stratosphere as an open system. The terms of these equations are interpreted as representing energy conversions and energy fluxes. The terms are evaluated for January 1958, for the mass from 100 mb to 10 ... |
