Generation and propagation of African squall lines
Quarterly Journal of the Royal Meteorological Society, 1984AbstractA study of squall lines affecting Minna, Nigeria during 1974–1976 emphasizes two particular aspects of their dynamics: that a strong jet around 650 mb is essential for their development, and that the forward edge of the squall line moves slightly faster than the maximum jet speed.

Mesoscale Structure of an Oklahoma Squall Line
Monthly Weather Review, 1981Abstract A squall line, which passed through the National Severe Storms Laboratory measonetwork in Oklahoma on 26 April 1969, is analyzed to determine the mesoscale structure. The analyses are based on data from 23 rawinsonde ascents, 29 automatically recording surface stations, and radar PPI coverage.

Upper Air Conditions after a Line-Squall
Nature, 1923METEOROLOGISTS are indebted to Wing-Commander L. W. B. Rees for some very valuable observations during two aeroplane ascents at Cranwell (Lines.) on October 19, showing the change which took place in upper-air conditions during the passage of a “linesquall” or, in the phraseology of Bjerknes, a “cold front.” Observations of this kind are sufficiently ...

Tropical Squall Lines and Mesoscale Convective Systems
2013Passage of tropical squall lines is a common phenomenon in the rain areas of the tropics. These systems form over the land areas and even continue over the ocean for several days. The meso/beta scale (20–200 km) is a common scale of organization of convection within what are called the Meso Convective Systems (MCS).

A Wave-CISK Model of Squall Lines
Journal of the Atmospheric Sciences, 1984Abstract The wave-CISK model of Raymond incorporating lag effects in the updraft and downdraft is implemented as an initial value problem in physical space. Examples of both midlatitude and tropical squall lines are successfully simulated. Diagnosis of the model shows that condensational heating in the updraft is the primary driving mechanism of a ...

A PROPOSED MECHANISM OF SQUALL LINES: THE PRESSURE JUMP LINE
Journal of Meteorology, 1950Abstract The squall line of 16 May 1948 in the area of the Cloud Physics Project, U. S. Weather Bureau micro-meteorological network of weather recording stations near Wilmington, Ohio, is analyzed by means of one-minute synoptic maps, x–t diagrams and isochrone maps. The relative behavior of the pressure jump, wind shift, temperature fall, maximum wind
