These eye-like features are most normally found in intensifying tropical storms and hurricanes of Category 1 strength on the Saffir-Simpson scale. For example, an eye-like feature was found in Hurricane Beta when the storm had maximum wind speeds of only 80 km/h (50 mph), well below hurricane force. [26]
A Hurricane Hunters engineer captured video from inside Hurricane Helene's eye Wednesday after it formed along the Gulf of Mexico.
When Hurricane Wilma was near peak intensity during the 2005 Atlantic hurricane season, its eye was not even 3 miles across. Small eyes like this are often referred to as pinhole eyes by ...
Concentric eyewalls seen in Typhoon Haima as it travels west across the Pacific Ocean.. In meteorology, eyewall replacement cycles, also called concentric eyewall cycles, naturally occur in intense tropical cyclones with maximum sustained winds greater than 33 m/s (64 kn; 119 km/h; 74 mph), or hurricane-force, and particularly in major hurricanes of Saffir–Simpson category 3 to 5.
Mesovortices visible in the eye of Hurricane Emilia in 1994. An eyewall mesovortex is a small-scale rotational feature found in an eyewall of an intense tropical cyclone. Eyewall mesovortices are similar, in principle, to small "suction vortices" often observed in multiple-vortex tornadoes. In these vortices, wind speed can be up to 10% higher ...
The StreamSonde is a lighter and smaller take on the dropsonde, a bundle of instruments in a large cylinder to measure conditions inside a hurricane that has been the research workhorse of the ...
However, the National Hurricane Center (NHC) later started used the Annular Hurricane Index for the purpose of assessing annular tropical cyclones. The index takes into account the cloud height of the storm, the radii of the eye, and other similar factors, using satellite imagery, and then produces a number, with the maximum value on the scale ...
The ominous eye of Hurricane Milton is visible in stunning detail from outer space in a timeplapse video released Tuesday by NASA.. From 275 miles above Earth, the powerful storm can be seen ...
