Hurricane Dorian

I’ve been taking some interest in the Category 5 Hurricane Dorian, which passed over the Bahamas yesterday, and is expected to turn north thereafter.

Even though it’s the biggest storm for years, nobody seems to have been killed by it in the Bahamas. In a NASA report yesterday:

The eye of Category 5  Hurricane Dorian was directly over the Abacos Islands as of the National Hurricane Center’s (NHC) 2:00 pm EDT advisory and is now heading towards Grand Bahama Island. The hurricane is located about 185 miles (295 km) east of West Palm Beach, FL. Maximum sustained winds are 185 mph (295 km/h) with gusts over 200 mph. Dorian is moving west at 7 mph.  The central pressure is 911 Mb which continues to lower meaning the storm continues to intensify. This is the fifth Category 5 hurricane sustained in the last five years.

ABC news report from Marsh Harbour in the Abacos Islands:

Using radar images, I constructed a map showing the eye of the hurricane passing  westward over Marsh Harbour yesterday. I estimated that the eye had a diameter of 31.5 kilometres.

It seems that the strongest winds in a hurricane are in the front right quadrant of the eyewall.  Since the hurricane was moving westwards, the front right quadrant of the eyewall would have been over the sea north west of Marsh Harbour. This may explain why nobody was killed.

It also seems that the greatest storm surges are found in the front left quadrant of the hurricane, so if Marsh Harbour may not have experienced the strongest winds, it seems it would have experienced the greatest flooding.

According to NASA, there seem to be a lot more hurricanes/cyclones in the northern hemisphere than in the southern hemisphere:

Yesterday I found other videos of Dorian in the Bahamas here and here.

I suppose the global warming alarmists will have already started citing Dorian as proof of global warming.

One question: is there a depression in the atmosphere above the eye of a hurricane just like there’s a depression in the water over the plughole of an emptying bathtub?
