Correlation Between Winds and Pressure

#1 Postby mtm4319 » Thu Jul 14, 2005 7:42 pm

I know there isn't a perfect relationship, but can someone provide a rough translation between minimum central pressure and maximum sustained winds? The only thing I found on a Storm2K search was that a 950mb pressure is consistent with a borderline category 3/4 hurricane.

Thanks in advance.

As you said, this is a VERY rough estimate:


Category 1 65- 82 kt; 74- 95 mph | > 979 mb; > 28.91 "Hg
Category 2 83- 95 kt; 96-110 mph | 965-979 mb; 28.50-28.91 "Hg
Category 3 96-113 kt; 111-130 mph | 945-964 mb; 27.91-28.47 "Hg
Category 4 114-135 kt; 131-155 mph | 920-944 mb; 27.17-27.88 "Hg
Category 5 > 135 kt; > 155 mph | < 920 mb; < 27.17 "Hg

It will ALL vary according to the SIZE of the storm (smaller storms have higher pressures for maximum winds and vice-versa) and the SURROUNDING pressures (higher surrounding pressures creates more winds).
