Zonal Flow

Zonal Flow: West to East airflow, as opposed to Negative Zonal Flow which is East to West. The BBC is not responsible for the content of external websites.

zonal flow - (Also called zonal circulation.) In meteorology, the flow of air along a latitude circle; more specifically, the latitudinal (east or west) component of existing flow. Compare meridional flow; see zonal index.

Zonal flow Component of atmospheric circulation along a line of latitude, towards the east or west. Atmospheric circulation along, or approximately along, parallels of latitude ...

ZONAL FLOW The flow of air along a latitudinal component of existing flow, normally from west to east.

Zonal Flow: Large-scale atmospheric flow in which the east-west component, i.e., flow parallel to the latitude lines, is much greater than the meridional (north-south) component. Compare with meridional flow.

Zonal Flow - Large-scale atmospheric flow in which the east-west component (i.e., latitudinal) is dominant. The accompanying meridional (north-south) component often is weaker than normal. Compare with meridional flow.

Zonal Flow - It's when the winds in the upper levels of the atmosphere blow from coast to coast with little or no deviation. In other words, the jest stream creates a straight line.

Zonal flow-a wind flow that is pretty much in a west to east direction. Temperatures stay fairly close to normal in a zonal flow.

ZONAL FLOW- Flow of wind equal or nearly equal to the lines of latitude. ZONE FORECAST- A forecast for a particular region (often a forecast for certain cities, counties or parishes). ZL- Freezing Drizzle ...

Zonal Flow (Zonal Wind)- Large-scale atmospheric flow in which the east-west component (i.e., latitudinal) is dominant. Zone Of Maximum Precipitation- The belt of elevation at which the annual precipitation is greatest in a mountain region.

This weakens the zonal flow. MESOCYCLONE A area of rotation of storm size that may be found on the southwest part of a supercell. Its circulation is much larger than the tornado that may develop within it.

Z0060 Zonal circulation Zonal flow Component along a line of latitude, towards east or west, of an atmospheric circulation. Atmospheric circulation along, or approximately along, parallels of latitude. Z0070 Zonal flow (Z0060) ...

A west wind. Zonal Flow: A west to east movement of air masses. Zonda: A Fohen (Warm Wind) that is located in the mountain valleys of Argentina, South America. ZL: Freezing Drizzle. ZR: Freezing Rain.

MERIDIONAL FLOW Atmospheric circulation in which the north and south, or meridional, component of motion is unusually pronounced. This weakens the zonal flow.

Meridional Flow - Large-scale atmospheric flow in which the north-south component (i.e., longitudinal, or along a meridian) is pronounced. The accompanying zonal (east-west) component often is weaker than normal. Compare with zonal flow.

Large-scale atmospheric flow in which the north-south component (i.e., longitudinal, or along a meridian) is pronounced. The accompanying zonal (east-west) component often is weaker than normal. Compare with zonal flow. MESO ...

Atmospheric circulation in which the north and south, or meridional, component of motion is unusually pronounced. This weakens the zonal flow. MESOCYCLONE ...

Compare with zonal flow.MESOMesocyclone- A storm-scale region of rotation, typically around 2-6 miles in diameter and often found in the right rear flank of a supercell (or often on the eastern, or front, flank of an HP storm).
