A surface system with a horizontal wind speed of 75 ms-1 and a radius of curvature of 0.4 kilometer is observed in the atmosphere at 35°N latitude. Given a mean air density of 1.2 kgm-3:
a. Find the Ross by Number for the system. Find what type of system is this likely to be?
b. Find the pressure gradient of the system. Determine the relative central pressure of the system?
c. Find the most likely direction of rotation of the system (if any)?
