(a) Use the Saffir-Simpson Hurricane Wind Scale (see Table, p. 453) to determine the category of Hurricane Elena (Fig., p. 441).
▼Table Saffir-Simpson Hurricane Wind Scale
SCALE CATEGORY | WINDS (ONE MINUTE SUSTAINED) | SUMMARY* | |
mi/hr | knots | ||
1 | 74-95 | 64-82 | Very dangerous wands will produce some damage |
2 | 96-110 | 83-95 | Extremely dangerous winds will cause extensive damage |
3 | 111-130 | 96-113 | Devastating damage wall occur |
4 | 131-155 | 114-135 | Catastrophic damage will occur |
5 | >155 | >135 | Catastrophic damage will occur |
FIGURE Hurricane Elena over the Gulf of Mexico about 130 km (80 mi) southwest of Apalachicola, Florida, as photographed from the space shuttle Discovery during September 1985. Because this storm is situated north of the equator, surface winds are blowing counterclockwise about its center (eye). The central pressure of the storm is 955 mb, with sustained winds of 105 knots (121 mi/hr) near its eye.
(b) Would Hurricane Elena be classified as a major hurricane?
(c) If Elena were over the western Pacific, would it be classified as a super typhoon?
