It is a correction/adjustment to Geometric Altitude using
variation of gravity with latitude and elevation and hence it is also known as ‘Gravity
Adjusted Height’.

What is the altitude for the Antarctic?
the altitude is high, around 2194m.
When altitude increases does air density?
The density of the atmosphere decreases with altitude.
Which decreases as altitude increases?
As altitude increases pressure and temperature decrease.
What is the relationship between temperature and altitude in the exosphere?
as altitude increases temperature decreases
When altitude increases temperature does what?
Temperature decreases as altitude increases.
What is the Difference between geopotential altitude and geometric altitude?
Altitude in an aircraft is generally measured by the hydrostatic equation: p=rho*g*h, where p is the pressure at the point of measurement, rho is the density at the point of measurement, g is the acceleration due to gravity at the point and h is the height from a reference to that point (the reference is generally taken as sea level). Aircrafts use the hydrostatic equation to determine the height/ altitude because pressure can be easily measured with a pitot tube that planes have. So using a pitot tube the airplanes measure the pressure and with that they can put it into the equation and solve for the height. However, gravity is not the same at different altitudes and changes with respect to the altitude. It is very difficult for an airplane to measure gravity in the air. Therefore airplanes generally measure geopotential altitude. The geopotential altitude uses gravity at sea level and takes it to be constant. Whereas geometric altitude uses gravity at the point of measurement. Therefore P = rho*g0*h(geopotential) where g0 is the gravity at sea-level and h(geopotential) is the geopotential altitude and P=rho*g*h(geometric) where g is the gravity at the point of measurement and h(geometric) is the geometric altitude or the actual height above sea-level Notice that the pressure and rho are common in both equations -by floyd617

What is a rossby wave?
These are also known as planetary waves, and are simply waves in the geopotential height field of the atmosphere. There are typically 3-7 of the at any given time circling the hemisphere.

What is a non example of altitude?
Green is a non example of altitude.
Where are Rossby waves found?
They are found everywhere. These are also known as planetary waves, and are simply waves in the geopotential height field of the atmosphere. There are typically 3-7 of the at any given time circling the hemisphere.

How do you calculate the altitude of a triangle?
Let the given area is 10cm. Base of the triangle is 4 cm. altitude of triangle=? Area= 1/2 x Base x altitude 10= 1/2 x 4x altitude 10=2 x altitude 10/2= altitude 5= altitude Hence, altitude of the triangle is 5 cm.
How do you spell altitude in french?
altitude (fem.)
