Document Summary
Taino language of caribbean meaning god of evil . Term used in australia and in the indian ocean. Storm (tropical region) with sustained winds of 18 ms-1 to 33 ms-1. Tropical storm with sustained winds ranging from 33 ms-1 to 50 ms-1. Tropical storm with sustained winds exceeding 50 ms- 119-153 km/h (33 42. 5 m/s), > 980 mb. 154-177 km/h (42. 5 - 49 m/s), 965 979 mb. 178-209 km/h (49 58 m/s), 945 964 mb. 210-249 km/h (58 69 m/s), 920 944 mb. Greater than 249 km/h (> 69 m/s), < 920 mb. Tropical storms fueled by sea surface temperatures and latent heat release. 26. 5 oc threshold is necessary but not sufficient. Energy is transported as sensible and latent heat. Latent heat transport occurs when moist equatorial air moves poleward, cools, condenses and releases latent heat. Wind generates waves, increasing spray, increasing evaporation and latent heat -fuel for the storm.
