Two weather stations record air pressure. Weather station 1 is 100km north of weather station 2. The pressure at station 1 is 1023mb and at station 2 it is 1015mb. What is the pressure gradient between the two stations?

Question

Quizplus · Accepted Answer

The pressure gradient between the two stations can be calculated using the formula:
Pressure Gradient = (Pressure difference between two points/distance between two points)
Pressure difference between the two stations = 1023mb - 1015mb = 8mb
Distance between the two stations = 100km
Therefore, Pressure Gradient = 8mb/100km = 0.08 mb/km. 
Therefore, the correct answer is choice B.
