Comparison of Temperature Gradient Model Predictions with Recent Rainfall Trends in the Sahel
Publisher: American Meteorological Society
Abstract: Using the temperature departure data of Angell and Korshover (1978), models relating the movement of the Intertropical Convergence Zone (ITCZ) to hemispheric temperature gradients are compared with rainfall data from the ...
Correlations between Rainfall and Sea Surface Temperature during GATE
Publisher: American Meteorological Society
Abstract: Lead and lag correlation coefficients are obtained between sea surface temperature and rainfall in the B-scale region during GATE. Significant negative correlation is found for 1-day lag and positive correlation for 1-day ...
A New Criterion for Locating the Subtropical High in West Africa
Publisher: American Meteorological Society
Abstract: After reanalyzing the potential temperature data of Peixoto (1958, 1960), a criterion is derived for locating the mean latitude of the subtropical high over West Africa. Using this criterion, it is found that the subtropical ...
Turbulence Kinetic Energy Budget Profiles Derived from Doppler Sodar Measurements
Publisher: American Meteorological Society
Abstract: Doppler sodar wind measurements made in light wind conditions in September 1979 near a power plant in Turbigo, Italy, are used to derive terms in the turbulence kinetic energy (TKE) budget. Measurements on five days are ...
Convectivc Elements in the Marine Atmospheric Boundary Layer. Part II: Entrainment at the Capping Inversion
Publisher: American Meteorological Society
Abstract: Data from two aircraft flights in the marine atmospheric boundary layer are analyzed in an investigation of entrainment processes at the top of the well-mixed layer. Both days had strong wind shear across the inversion, ...
Convective Elements in the Marine Atmospheric Boundary Layer. Part I: Conditional Sampling Statistics
Publisher: American Meteorological Society
Abstract: The properties of updrafts and downdrafts through the entire depth of the marine atmospheric boundary layer are investigated using conditional sampling based on an indicator function derived from the vertical velocity time ...
Conditional Sampling of Updrafts and Downdrafts in the Marine Atmospheric Boundary Layer
Publisher: American Meteorological Society
Abstract: The properties of updrafts and downdrafts in the lower third of the marine atmospheric boundary layer (MABL) over the central Pacific Ocean are investigated using a conditional sampling technique. When the drafts are ...
Relations between the Z Criterion for the Subtropical High, Hadley Cell Parameters and the Rainfall in Northern Ghana
Publisher: American Meteorological Society
Abstract: We use radiosonde data from Tamale in northern Ghana to evaluate the Z criterion latitude φz. We find it correlates well with other Hadley cell parameters since its variations are apparently controlled by the meridional ...
