Thanks! Yikes. Rita's a lot lower at the moment, right? Jeez louise.
I've been trying hard to keep up with this thread but it's moving too fast for me right now.
Would you please explain just what is meant by the above italics?
What is "mb"? What is the correlation of the 27.49 inches?
I apologize for asking these questions but perhaps somebody could give us a crash course in just what the hell all this means?
Thanks for any advice or input.
1 atmosphere is about 14.7 psi. It's also 1000 millibars or one Bar (Barometric pressure).
Millibars is just a different measurement for inches of mercury for measuring atmospheric pressure.
The lower the pressure the stronger a storm is, generally.
Meterologists use millibars almost exclusively.
Interestingly it's not the official metric name, which is Hectopascals; 1 Hectopascal is the same as one millibar though. Why this is so is a long and confusing story.)
inches, is inches of mecury in a barometric gauge
mb is millibars, the metric measurement of barametric pressure.
as we get lower and lower in millibars it indicates storm strenght
see the tables at the start of the article.
its pressure is now very low like Katrina and other super storms
