Midtropospheric Anticyclonic Vortex Street Associated with a Cloud Band near a Cold Front

Precipitation Associated with a Cold Front , December 7 - 9 / 1956

During the period December 7-9, 1956, a slow-moving cold front over the Central States brought prolonged precipitation to an area extending from' northern Texas northeastward into New England (fig. 1). Amounts of over 3 inches accumulated in portions of southern Illinois and Indiana. Accumulations of 1 inch or more were reported from northeastern Oklahoma to Lake Erie,. Prior to this period, a ...

Roll Clouds Associated with an East Asian Cold Front

On 11 January 1998, a cold front formed in southeast China as a result of a cold-air outbreak in northeast Asia. During this synoptic development, a series of roll clouds (along the SW–NE direction) was observed in East Asia; some of the clouds stretched for over a thousand kilometers. This roll cloud formation moved southeastward across Taiwan, the Ryukyu Islands, and Japan, and eventually int...

Structure of a Flame Front Propagating against the Flow Near a Cold Wall

North - south flows at 47 AU : A heliospheric vortex street ?

A north-south flow pattern with a recurrence period approximately equal to the solar rotation period was observed by Voyager 2 during 1995 at 47 AU, nearly a solar cycle after the north-south flows were first observed near 21 AU during 1986. The north-south flow deflections observed during 1995 were less regular than those observed in 1986. One finds the same qualitative associations between th...

Thermal Field Around a Circular Cylinder with Periodic Vortex Shedding

A numerical study is carried out to investigate the laminar forced convection heat transfer from a circular cylinder. The fluid is assumed to be incompressible, the Reynolds number ranged from 0.1 to 1000, and the Prandtl number was equal to 0.7. The range of study includes heat transfer in creeping flow (Re40). The equations were discretized by a control-volume-based finite difference techniqu...
