Explanation:
The air coming from the Gulf of Mexico loaded with moisture has a greater weight, so a density greater than the air in the city, so its pressure is higher than the air pressure in the city.
If we consider that the speed in both airs is the same, we can see that
P₁ - P₂ = ½ (ρ₂ - ρ₁) v².
Therefore there is a negative variation in atmospheric pressure, so the pressure must decrease in cities and fields
