BLOCKING HIGH The development of a warm ridge or cutoff high aloft at high latitudes which becomes associated with a cold high at the surface, causing a split in the westerly winds.
Blocking high
An intense or strong high pressure system that occasionally forms much further south than usual and remains almost stationary for days, weeks or even months.
Blocking High- A high pressure area (anticyclone), often aloft, that remains nearly stationary or moves slowly compared to west-to-east motion. It blocks the movement eastward movement of low pressure areas (cyclones) at its latitude..
block - Same as blocking high.
blocking - 1. The obstructing, on a large scale, of the normal west-to-east progress of migratory cyclones and anticyclones.
The strong blocking high weakens and shifts westward. A split in the North Pacific jet stream develops, ...
It is an example of a blocking high. OPAQUE A condition where a material, such as a cloud, blocks the passage of radiant energy, especially light. Opaque sky cover refers to the amount of sky cover that completely hides all that might be above it.
BLOCKING - The inhibition of the forward progression of one weather system by another. Commonly a high pressure system that blocks or deflects the motion of an advancing low pressure area is called a BLOCKING HIGH.
CUT-OFF HIGH A warm high which has become displaced and is on the polarward side of the jet stream. It occurs mostly during the spring and is most frequent over northeastern Siberia, Alaska, and Greenland. It is an example of a blocking high.
It frequently occurs in the late winter and early spring in the Northern Hemisphere. The name comes from its resemblance to the Greek letter, Omega, when analyzed on upper air charts. It is an example of a blocking high.
This feature is also called a "blocking high" because it prevents the normal progression of weather systems and fronts from west to east. Omega highs are more prevalent in the spring, summer, and fall than they are during the winter months.
It is an example of a blocking high.Onshore BreezeA wind that blows from a body of water towards the land. Also known as a seabreezeOnshore FlowOccurs when air moves from sea to land, and is usually associated wtih increased moisture.
