aslkahuna Posted October 19, 2014 Share Posted October 19, 2014 Thanks for the reply. I was not aware that there was an elevated station that measured a higher sustained wind than the 98 mph I referenced. That aside, I stand by everything else I wrote in that post, and totally agree with everything else you stated.Important to remember- Bermuda reports 10 minute sustained winds not 1 minute like us.

apm Posted October 19, 2014 Share Posted October 19, 2014 What's the furthest north in the Atlantic a Hurricane has been recorded? Gonzalo's got to be close if not it. http://www.nhc.noaa.gov/text/refresh/MIATCDAT3+shtml/191434.shtml? Impressive! Link to comment Share on other sites More sharing options...

Chinook Posted October 19, 2014 Share Posted October 19, 2014 These are the reports from Cape Race, Newfoundland from 0900z to 1100z. The pressure dropped to 973.7mb, wind gusts peaked at 54 knots (62mph) and 48 knots (55mph) as the wind shifted E to NW.

Amped Posted October 19, 2014 Share Posted October 19, 2014 Faith 1966 60N ? I assume they haven't done reanalysis of that year yet. Link to comment Share on other sites More sharing options...
Sickman Posted October 19, 2014 Share Posted October 19, 2014 60N ? I assume they haven't done reanalysis of that year yet. Yeah, 61.1N seems a tad unrealistic, unless there was an underwater volcanic eruption south of Iceland or something. More recently, Alberto in 2000 made it to 53.2N as a TC.

Chinook Posted October 20, 2014 Share Posted October 20, 2014 I would guess that these images are (smoothed) 85 GHz horizontal brightness temperatures from SSMI satellite passes. I think that a low brightness temperature under 160K (red stuff), amongst 250K brightness temperatures (blue stuff) would mean that it's just some bad data. It looks like a U-shape because the microwave radiometer does a conical scan of the earth's surface (kind of like a cone intersecting a plane.) It doesn't take long to do one scan. As per Wikipedia, "The spin rate of the SSM/I provides a period of 1.9 sec..." So this weird group of sub-160 Kelvin temperatures only represents about 6 seconds of data that went bad. This is fairly normal to see weird crap like this, once or twice per orbit. http://en.wikipedia.org/wiki/Special_sensor_microwave/imager a couple of examples of crap data from SSMI satellites (note the U-shaped holes in the data. It was flagged as bad data) The wide white areas are areas that didn't get covered on successive ascending passes. Link to comment Share on other sites More sharing options...

Theres some uncertainty as to whether Debbie in 1961 was still tropical or not when it hit Ireland (53N). http://en.wikipedia.org/wiki/Hurricane_Debbie_(1961) Link to comment Share on other sites More sharing options...
Chinook Posted October 20, 2014 Share Posted October 20, 2014 Do you want me to remove my post, since it is cluttering things up a bit now? My post was regarding this: I responded to some weird data, (or conspiracy theory,) in the microwave imagery of Gonzalo. It was just some bad data that happens about once per orbit on SSM/I microwave imagers. Link to comment Share on other sites More sharing options...
OSUmetstud Posted October 21, 2014 Share Posted October 21, 2014 Based on these observations, the eyewall passed over Bermuda, and the center of the eye was just west of Bermuda. There was a brief southerly wind while in the eye, with easterly and westerly just before and after. The NHC mentioned the center of the eye appeared to go over Devonshire Parish near the center of the islands. TXKF is located in St. David's...on the east end.

eurojosh Posted October 21, 2014 Share Posted October 21, 2014 Three killed in the UK today by the remains of Gonzalo. Some pretty amazing photos here, including shelf clouds and a waterfall being blown uphill. http://www.dailymail.co.uk/news/article-2801196/hurricane-gonzalo-hits-75mph-winds-bringing-travel-chaos-uk-heathrow-cancels-10-flights.html Link to comment Share on other sites More sharing options...
