    Take it as you will but I doubt they are naming the hurricane specifically after you. ;) I believe the correct phrase is "sharing a name."

    They've been having the option to to click to the old format but I don't see that anymore. You can click on "Lite" at the top and get simple site that has a quicker upload.

    Ah, cool, didn't know about that one. Thank you, most honorable sir.
    :confused: don't you mean DOWNload?

    Upload is for a user transferring something to them, not them down to us.

    Also, WAYBACKMachine has its last crawl under the old format as December of 2010:

    :( I miss that format.

    New Paper: Maue (2011) Recent historically low global tropical cyclone activity:

    During the past 6-years since Hurricane Katrina, global tropical cyclone frequency and energy have decreased dramatically, and are currently at near-historical record lows. According to a new peer-reviewed research paper accepted to be published, only 69 tropical storms were observed globally during 2010, the fewest in almost 40-years of reliable records.
    Furthermore, when each storm's intensity and duration were taken into account, the total global tropical cyclone accumulated energy (ACE) was found to have fallen by half to the lowest level since 1977.

    In his new paper, "Recent historically low global tropical cyclone activity", Dr. Ryan Maue, a meteorologist from Florida State University, examined the last 40-years of global hurricane records and found strikingly large variability in both tropical cyclone frequency and energy from year-to-year. Since 2007, global tropical cyclone activity has decreased dramatically and has continued at near-historical low levels. Indeed, only 64 tropical cyclones were observed globally in the 12-months from June 2010 - May 2011, nearly 23-storms below average obliterating the previous record low set in 1977.

    On average, the North Atlantic including the Gulf of Mexico and Caribbean Sea accounts for about 1/8 of total global tropical cyclone energy and frequency. However in 2010, the Atlantic saw 19 tropical storms, of which 12 became hurricanes as expected (and forecasted) due to the intense La Nina event and continued positive Atlantic Multidecadal Oscillation (AMO). The Atlantic Ocean's accumulated cyclone energy (ACE) corresponded to about 1/3 of the global calendar year output while the Western North Pacific typhoon season experienced a record few number. Seasonal forecasters of Atlantic hurricanes expect a similar but somewhat tempered outcome for the 2011 season, which has yet to get underway.

    While the North Atlantic continued a 16-year period of above-normal activity in 2010, the North Pacific including the warm tropical waters from China to Mexico experienced the quietest tropical cyclone season in at least 40-years of historical records. Similarly, the most recent Southern Hemisphere cyclone season, except for the disastrous impacts of Yasi, was also notably below average. All told through June 27, 2011, overall global accumulated cyclone energy and frequency has settled into a period of record inactivity.

    Invest 90 in the carribeans. Intensity forecast has it at 60 to 70 mph winds by middle of the next week.

    Dry air will continue to be a problem for 90L through Sunday, but once it finds a moister environment near the Bahama Islands early next week, it could develop. However, the expected track of the disturbance takes it over the rugged terrain of Hispaniola, which would inhibit development. Furthermore, wind shear is expected to rise to the moderate range, 10 - 20 knots, on Saturday, and could increase further by Monday, according to most of the computer models. Of the latest 00Z and 06Z runs of the four reliable models for predicting formation of a tropical depression, only the NOGAPS model shows development of 90L. The NOGAPS predicts the wave could attain tropical depression status on Tuesday, over the northwestern Bahama Islands just off the coast of Southeast Florida. The other models generally depict too much wind shear for the wave to develop. Right now, the deck appears stacked against development for 90L through at least Monday. NHC is predicting a 20% chance of development by Sunday. The eventual track of 90L next week has been trending more to the south in recent model runs, as they are generally depicting a weaker trough of low pressure developing over the Eastern U.S. This reduces the chances 90L will move up the U.S. East Coast, and increases the chances that it will enter the Gulf of Mexico.

    TROPICAL WEATHER OUTLOOK
    NWS NATIONAL HURRICANE CENTER MIAMI FL
    200 PM EDT FRI JUL 22 2011

    FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

    1. A TROPICAL WAVE LOCATED ABOUT 325 MILES EAST OF THE LESSER ANTILLES
    IS PRODUCING SCATTERED SHOWERS AND THUNDERSTORMS. SLOW DEVELOPMENT
    OF THIS SYSTEM IS POSSIBLE DURING THE NEXT COUPLE OF DAYS AS IT
    MOVES WESTWARD TO WEST-NORTHWESTWARD AT 15 TO 20 MPH. THERE IS A
    LOW CHANCE...20 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL
    CYCLONE DURING THE NEXT 48 HOURS. REGARDLESS OF DEVELOPMENT...
    BRIEF PERIODS OF LOCALLY HEAVY RAINFALL AND GUSTY WINDS SHOULD
    SPREAD ACROSS PORTIONS OF THE LESSER ANTILLES THIS AFTERNOON AND
    TONIGHT.

    ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
    NEXT 48 HOURS.

    Invest 90L spiked in thunderstorm activity and circulation yesterday, leading NHC to re-invest the system. 90L is still south of Cuba moving ever-so-slowly to the west. While low level (850mb) circulation has increased since yesterday morning, the system is tilted southeast with height. This is likely due to the westerly wind shear it's facing right now. As the system moves into the Gulf, shear will become more favorable (if there's shear present, easterly is better than westerly). The wave is still moist and moisture is expected to remain high (4 to 5.5 g/kg specific humidity) as it tracks into the Gulf of Mexico.

    Again this morning, none of the models are suggesting meaningful development of Invest 90L. However, the GFS (finally) has come around to resolving the circulation at all. Dr. Rob Carver and I spoke this morning, and we came to the conclusion that the lack of observations in this region, combined with the small size of the system, is causing the models to not have the best handle on the situation. The Hurricane Center has a Hurricane Hunter mission scheduled for 18z (2pm EDT) tomorrow, after which we could see the models starting to favor development again. Today the Hurricane Center is forecasting a 20% chance of development over the next 48 hours. I agree with that, but I also think that beyond 48 hours this wave is going to have a better shot at developing a closed circulation at the surface.

    Mr. Invest 90L, please do not come to Houston. I am going on vacation next week and would rather not have to worry about whether I will have a home to come back to.

    Thank you.

    Mr. Invest 90L. Do not develop...but please dump some rain on the Greater Houston area, even if macalu is out of town.

    Hugs & Kisses,

    MadMax
