Coriolis Force: How does the Earth's rotation modify the Wind?
Wind does not cross the isobars at right angles as the pressure-gradient force directs.
All free-moving objects, including wind, are deflected to the right of their path of motion in the Northern Hemisphere and to the left of their path of motion in the Southern Hemisphere.
The reason for this deflection is the Coriolis force:
where m is the mass and u is the velocity vector of a fluid parcel, and is the rotation vector of the Earth.
The magnitude of the Coriolis force is:
where is the latitude, f = 2 sin is called the Coriolis parameter, and u is the magnitude of the velocity.
The Coriolis force written in vector form clearly indicates that
It is directed at right angles to the direction of air flow.
It affects only wind direction, not the wind speed.
Its magnitude is affected by wind speed (the stronger the wind, the greater the deflecting force).
Its magnitude increases from zero at the Equator to a maximum at the poles.
The Coriolis force thus has the effect of deflecting air flow. It also has the effect of deflecting ocean currents.
What else can I help you with?
What is it called when the paths of winds and ocean currents seem to curve because of the earths rotation?
It's called the 'Coriolis effect'. In the northern hemisphere, they rotate clockwise. South of the equator, they rotate counter-clockwise.
Which equinox occurs in september in the northern hemisphere?
The fall equinox occurs in September in the Northern Hemisphere.
In the northern hemisphere the sun sets in the what?
In the Northern Hemisphere, the Sun apparently rises in the east and sets in the west. In the Southern Hemisphere, it is the other way around. The Sun rises in the west and sets in the east. Note that the Sun does not actually move, it is Earth that makes it appear to move.
Is the equader someting to do with the hemisphere?
The Equator, the imaginary line like a belt round the Earth, divides the world into two hemispheres. the Northern Hemisphere and the Southern Hemisphere
How many constellations are there in the northern hemisphere?
first question, how many asses can you find in your dick, then there is your answer, NONE
Do high pressure go clockwise?
In the northern hemisphere, yes.
In a low pressure system which direction do winds in the northern hemisphere blow?
In the northern hemisphere the circulation around a high is clockwise. In the southern hemisphere the circulation around a high is counter-clockwise.
Which direction does air flow in a cyclone?
Counter-clockwise in the Southern Hemisphere, and clockwise in the Northern Hemisphere.
Do the Northern Hemisphere travel clockwise or counterclockwise?
clockwise
What direction is the Coriolis effect in the northern and southern hemisphere?
In the Northern hemisphere, the direction is clockwise... In the Southern, it turns anti-clockwise.
Do tornadoes go clockwise?
Tornadoes in the northern hemisphere usually rotate counterclockwise, while tornadoes in the southern hemisphere typically rotate clockwise. This is due to the Earth's rotation and the Coriolis effect.
Do currents in the northern hemisphere flow clockwise?
In the northern hemisphere, ocean currents generally flow clockwise due to the Coriolis effect, which is caused by the Earth's rotation. This effect causes moving fluids to curve to the right in the northern hemisphere and to the left in the southern hemisphere.
How do anti-cyclones spiral in the northern hemisphere?
Anticyclones in the northern hemisphere rotate clockwise.
What direction do surface winds circulate in a high pressure system in the northern hemisphere?
They circulate clockwise in the Northern Hemisphere, and counter clockwise in the Southern Hemisphere.
What direction does a cyclone spin in the northern hemisphere?
A typhoon in the northern hemisphere rotates counter-clockwise, in contrast to a typhoon in the southern hemisphere which rotates the other way (i.e., clockwise) as explained by the Coriolis effect.
Do tornados spin clockwise?
Most tornadoes in the northern hemisphere spin counter clockwise while most in the southern hemisphere spin clockwise.
Which directions do tornadoes spin?
Tornadoes nearly always spin counterclockwise if they are in the northern hemisphere and clockwise if they are in the southern hemisphere.
