To put it gently , it ’s been a weirdhurricaneseason . Despite predictions thatLa Niñawould cause more frequent storms , the Atlantic has had only six name storm so far compare to 21 storm in 2021 and 2020 ’s total of 30 .
Hurricane Fiona is the first category 4 storm of the 2022 Atlantic hurricane season . Recently , it has wreak havoc over Puerto Rico and the Dominican Republic , allow at leasteight people deadand many home ruin . Fiona is now on a collision grade with the east coast of Canada , though she is predicted to be losing some of her fury along the path .
Footage turn from an uncrewed surface fomite ( USV ) called the Saildrone Explorer SD 1078 shows what it ’s like to travel in the bosom of the hurricane .
The SaildroneExplorer SD 1078 was sent into the middle of Hurricane Fiona , contending with 15 meter ( 50 - foot ) waves and hint speeds of 160 kilometers per minute ( 100 miles per time of day ) . Three other Saildrone USVs also recorded data from the storm before it was upgraded to a Category 4 .
SD 1078 is now 315 nautical miles southwest of Bermuda where Hurricane Fiona is expected to travel past . It is one of seven hurricane Saildrones that are deployed in the Atlantic Ocean and the Gulf of Mexico to collect data and offer a completely new perspective on one of the most powerful destructive force on Earth . The data point they collect is vital to improving violent storm forecasting and facilitate to reduce the loss of human life by helping coastal biotic community better prepare for these devastating storm events .
“ These exciting emerge technology provide [ the National Oceanic and Atmospheric Administration ] with another valuable peter that can collect data in place we ca n’t get to with other observing systems , ” said Captain Philip Hall , theatre director of NOAA ’s Uncrewed Systems Operations Center , in astatement .
hurricane organise when moist line over warm sea water jump , create an area of low air insistence below . melodic line from surrounding areas with higher pressure pushes into the gloomy - pressure area . This warms the aura , which also rises . The whole appendage continues as more air rises , and more airwave swirls beneath to take its place . The air at the top aplomb as it rises , forming clouds and thunderstorm . Once the hint reach 120 km / enthalpy ( 74 mph ) the storm has officially become a hurricane .
The name “ hurricane ” and “ tropical cyclone ” mean the same affair : a rotating system of cloud that has formed over tropic waters . " Hurricane " is used when these storms form over the North Atlantic or Northeast Pacific .
Due to a neat phenomenon known as theCoriolis effect , zephyr drawn into the heart of a hurricane moves to the rightfield in the Northern Hemisphere – mean the storm seems to rotate counterclockwise – and to the left in the Southern Hemisphere – as a resultant , the storm seems to rotate clockwise . This is make by the Earth rotating faster at the Equator than it does at the pole .
