What direction does a meridional wind flow?
Zonal flow is defined as west to east or east to west, while meridional flow indicates north-to-south or south-to-north air motion.
What causes meridional winds?
Here we show that this change in the meridional wind field is caused by strengthened zonal mean westerlies in the sub-tropical upper troposphere, which alters the character of intermediate-scale stationary waves.
What is a meridional?
Definition of meridional (Entry 1 of 2) 1 : of, relating to, or situated in the south : southern. 2 : of, relating to, or characteristic of people living in the south especially of France. 3 : of, relating to, or situated on or along a meridian.
What is meridional section?
The meridional section plane is a section through the centre of rotation of an impeller.
What is zonal and meridional winds?
Zonal flow follows a pattern along latitudinal lines, latitudinal circles or in the west–east direction. Meridional flow follows a pattern from north to south, or from south to north, along the Earth’s longitude lines, longitudinal circles (meridian) or in the north–south direction.
What is meridional plane?
For a rotationally symmetric system, meridional rays lie in the plane containing the lens axis and an object point lying to one side of the axis. This plane is called the meridional plane. If the object point lies on the axis, all rays are necessarily meridional.
How do you calculate wind direction U and V?
Wind: u and v Components
- md = 270 − wwd.
- u = ws * cos(θ)
- v = ws * sin(θ)
- ws = sqrt(u2+v2)
What is meridional temperature gradient?
The meridional gradients are calculated as the latitudinal differential change between 10° and 17°N, over the same longitude. Then, the result is averaged for all the longitudes within the area enclosed by 83°–63°W. The SST area average is estimated for the same region.
What is a meridional section?
What is meridional shape?
The meridional plane describes the shape and size of the blade and shows information about R and Z in the cylindrical coordinate system. Because the meridional plane determines the diameters of the blade at the inlet and outlet and the curves of the hub and shroud, it is critical in impeller and diffuser design.

What is zonal SST gradient?
The equatorial Atlantic zonal sea surface temperature (SST) gradient, which has significant climatic and biogeochemical effects, is closely associated with the equatorial Pacific zonal SST gradient through Walker circulation on seasonal and interannual time scales.
What determines meridional heat transport in climate models?
The annual mean maximum meridional heat transport (MHTMAX) differs by approximately 20% among coupled climate models. The value of MHTMAX can be expressed as the difference between the equator-to-pole contrast in absorbed solar radiation (ASR*) and outgoing longwave radiation (OLR*).
What is meridional wind?
The windor wind component along the local meridian, as distinguished from the zonal wind. In a horizontal coordinate systemfixed locally with the xaxis directed eastward and the yaxis northward, the meridional wind is positive if from the south, and negative if from the north.
What is meridional flow in geography?
Meridional flow follows a pattern from north to south, or from south to north, along the Earth’s longitude lines, longitudinal circles (meridian) or in the north–south direction. These terms are often used in the atmospheric and earth sciences to describe global phenomena, such as “meridional wind”, or “zonal average temperature”.
What is the difference between zonal and meridional component?
For vector fields (such as wind velocity ), the zonal component (or x – coordinate) is denoted as u, while the meridional component (or y -coordinate) is denoted as v . ^ “Zonal”. Glossary of Meteorology.
What is the direction of wind?
The first thing we need to understand is that wind direction is stated as the orientation of the wind’s direction of movement. For example, if the wind is blowing from the southeast and is blowing towards the northwest, it is referred to be a southeast wind.
