![]() The anemometer for NOAA buoy 42058 recorded winds at 5 meters height, so there may be higher winds at 10 meters, but there is no indication of any problem with that instrument.Īircraft do not use anemometers, they make wind estimates using entirely different instruments. If the anemometer is recording 64 knot wind speed for one minute, then you have a category one storm for that minute. ![]() A hurricane is defined in the US as sustained surface winds at for one minute. Mechanical anemometers are the only consistently reliable instruments to determine those speeds, which is why they are used today. It’s simple, you have the measure the wind speed at 10 meters above the ground to say how much damage occurs to structures located on the ground. How those winds should be measured is defined by the creators of the scale. The Saffir-Simpson scale was created to define how much ground damage can be expected from defined sustained winds measured at 10 meters above the ground. Typically, the eyewall module will be tasked within 48 hours of a forecasted hurricane landfall. In this case, the outer of the two releases should be made at the RMW, with the second release following as soon as possible. If possible, and when resources and safety permit, two dropwindsondes, spaced less than 30 seconds apart, should be deployed on the inbound leg on the side of the storm believed to have the highest surface winds (normally the right-hand side). If the radar presentation is suitable, the inner edge of the radar eyewall may be used to identify the release point. The releases should be made at or just inward (within 12 km) of the flight-level radius of maximum wind (RMW). While executing a standard alpha pattern to satisfy a fix requirement, one sounding will be taken during each inbound and outbound passage through the eyewall (except as noted below), for a total of four soundings. Sea, which reported a minimum pressure of 943 mb and light windsĥ.8.4.1. Has recently passed over NOAA buoy 42058 in the central Caribbean Has been reduced to 115 kt for this advisory. Using a blend of the aircraftĭata and recent satellite intensity estimates, the initial intensity Wind maximum in the aircraft data, but the crew reported that theĮyewall was open to the southwest. Not clear from microwave imagery if the reduction in winds is the The Air Force Reserve reconnaissance mission that ended shortlyīefore 0600 UTC did not find flight-level or surface winds as highĪs reported during the previous flight yesterday afternoon. NWS NATIONAL HURRICANE CENTER MIAMI FL AL142016 The problem is not us, it is everybody else. Woild not rely on our 4WD Hybrid SUV to escape via roads. Not to mention the guest room sealable (ducktape) bathtub. ( It did take 18 months to repair our pool deck.) We have 7 days rations and bottled water in the go bag plus multilple gallon collapsed storage containers, fillable in 15 minutes, for flushing toilets. Only 4 days of Wilma power down except for building emergency gensets. Stupid to get on exposed highway versus hardened Cat 5 new construction. Last hit was Cat 3 Wilma, dirty side, 2005, and we survived nicely. So much for dinner table conversations.Ģ.Live now on Fort Lauderdale beach about 50 meters from Atlantic ocean and potential storm surge. ![]() Worst trip was so violent over 24 hours that the plane landed with his rudder bent 17 degrees out of true, and so was scrapped. Father was a Pacific Typhoon hunter, 409th off Guam, flying instrumented B29s into those things back then. ![]() Anyone follow this closer than me? Makes me wonder if the cagw is getting lower cased and swept under the rug? encouraging?īeen Tracking Mattew every 4 hours since days. I also thought I remembered a climate change tab/faq on the site which (again rapidly) did not find. Today I quickly searched the blog for the usual suspects global warming, climate change, unprecedented. But I never go there until tropical storms because 5 or so years ago the site was rabidly CAGW. I still think Jeff Masters understands the modeling and the storms better than anyone that I’ve seen (in a free service). Tangential, but it’s time for my yearly weather underground rant with a twist. Well right now the category 3/4 within 2 degree tracks all over the place so no help there. I’m not sure why but the historics sometime show fairly consistent patterns. I have no idea if it’s effective or not but I eyeball the model paths and then look to the historic tracks as kind of a confidence measure. Correct but a little more explanation the ground speed winds are generally faster where you get to add the wind field to the storm motion and slowed on the opposite side. ![]()
