What is a prevaling wind?
The direction from which the wind is mainly blowing from.
What are lines joining areas with equal air pressure called?
isobars
What is the harmattan in Things fall apart?
The harmattan is a dry Saharan wind from the direction of the Sahara desert.
What is a Long sand ridge that are oriented nearly parallel to the prevailing wind is called?
A longitudinal dune is a large, elongated dune lying parallel to the prevailing wind direction.
What are lines on a map joining areas of similar air pressured called?
isobars
How are the spacing of isobars and wind speed related?
Distribution of isobars on a map is connected with the direction and speed of the wind. As the isobars grow closer together it shows a rapid change in barometric pressure, which can indicate a storm front approaching - and that usually means increased winds.
On a weather map wind speeds are related to?
the spacing of isobars is the correct answer
How can you use isobars to show us the direction of the wind?
The isobars are generated from mean sea level pressure reports and the pressure values are given in millibars.
Where on a weather map wind speeds are related to?
On a weather map, the lines of equal pressure (isobars) also illustrate the pressure gradient or change of pressure per distance. The higher the pressure gradient, the higher the winds speed. Thus, when the isobars are close together, the gradient is high, and winds are higher than where the isobars are further apart. Wind can also be affected by local considerations, hills, valleys, and buildings can modify the gradient wind's direction and speed.
What can isobars tell you about wind speed?
isobars measure speed. the closer the ba r the faster the wind speed
How can isobars be used to tell about wind speed?
Generally speaking, the closer the isobars are to one another, the faster the wind speed.
What does close spacing of isobars on the weather map represent?
Closely spaced isobars indicate large pressure changes over a small area and suggest strengthening winds.Widely spaced isobars portray a "flat" or weak pressure gradient typical of light-wind situations.
When isobars are close together this means that there will be?
High winds. The closer the isobars - the higher the wind speed will be.
How are isobars used?
in graphs to indicate lines of equal pressureIsobars show wind speed. The closer the isobars are spaced - the stronger the wind is.
What can isobars tell you about windspeed?
an isobar can tell you the wind mileage and the strength of the wind
How can you tell how hard the wind is blowing on a map?
isobars
What does it mean when isobars are spaced out?
It means the wind will be weak.
