Question

An air pressure contour line joins locations in a region having the same atmospheric pressure. The following is an air pressure contour plot of a geographical region. Contour lines are shown at $0.05$ bar intervals in this plot.

If the possibility of a thunderstorm is given by how fast air pressure rises or drops over a region, which of the following regions is most likely to have a thunderstorm?

• A. $P$
• B. $Q$
• C. $R$
• D. $S$

Comments

answer should be "R", in between .65 and .7 , there is very ess gap and due to which strom probability is highest in this reigon.

Please can you work out your steps...It'll be helpful too. :)

If the possibility of a thunderstorm is given by how fast air pressure rises or drops over a region,...

In R, we can see 3 lines with $3$ pressures - $0.65, 0.7, 0.8$. Maximum difference among them is $0.1$ which is larger than any other region ($0.5$). Therefore $R$, but not sure whether this approach is correct or not. 

Answer 1

R will be the answer
