Question

What is latitude longitude latitude pressure ?

Answer 1

because the air pressure in the metar station that is closer from your position has more weight to the calculus of the final air Pressure in you position. I also know the latitude and longitude of the three metar stations and I also know the distance between my position and those stations. 

Answer 2

Explanation:

Latitude is the measurement of the distance of a location on the Earth from the equator. If a place is away from the equator, it receives less sunlight and a rise in latitude leads to a reduction in air pressure and a drop in latitude means that air pressure increases because of the weight of the air column.
