Since 2009 the Hong Kong Observatory has divided typhoons into three different classifications: typhoon, severe typhoon and super typhoon. [20] A typhoon has wind speed of 64–79 knots (73–91 mph; 118–149 km/h), a severe typhoon has winds of at least 80 knots (92 mph; 150 km/h), and a super typhoon has winds of at least 100 knots (120 mph ...
During the Atlantic hurricane season, even before a tropical cyclone forms, there are words like “tropical wave,” “tropical disturbance,” “invest” and “potential tropical cyclone.”
Depending on its location and strength, a tropical cyclone is called a hurricane (/ ˈ h ʌr ɪ k ən,-k eɪ n /), typhoon (/ t aɪ ˈ f uː n /), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean.
Cross section of a mature tropical cyclone. A typical tropical cyclone has an eye approximately 30–65 km (20–40 mi) across at the geometric center of the storm. The eye may be clear or have spotty low clouds (a clear eye), it may be filled with low-and mid-level clouds (a filled eye), or it may be obscured by the central dense overcast.
Yes, a hurricane is the same as a typhoon, which is also the same as a cyclone. A “hurricane” occurs over the North Atlantic or over the central or eastern North Pacific oceans—in places ...
Severe weather can occur under a variety of situations, but three characteristics are generally needed: a temperature or moisture boundary, moisture, and (in the event of severe, precipitation-based events) instability in the atmosphere.
For the intensity scale, PAGASA lowered the threshold wind speed for classifying super typhoons from 220 km/h to 185 km/h and defined a super typhoon as an extreme tropical cyclone with 10-minute maximum sustained winds reaching 185 km/h or greater (the range of wind speed for typhoon category is consequently adjusted to 118–184 km/h).
Cyclone vs. hurricane vs. typhoon: These are all terms used to name the same type of tropical storms, it just depends what ocean the storm is in. In the Atlantic and Eastern Pacific Ocean, a storm ...
