A tropical depression or tropical low is a tropical disturbance that has a clearly defined surface circulation with maximum sustained winds of less than 34 kn (39 mph; 63 km/h). Within the Southern Hemisphere, the depression can have gale force or stronger winds in one or more quadrants, but not near the centre.
Frank works for NOAA and is trying to determine what type of tropical disturbance is occurring in two ocean regions in the Northern Hemisphere, Region A and Region B. Both regions are showing circulation, but the wind in Region A is 35 mph and the wind in Region B is 50 mph.
Which region is experiencing a tropical depression, Region A or Region B?
