Document Summary
Cyclones: what are they: area of low atmospheric pressure characterized by rotating winds, rotation is, counter clockwise in the northern hemisphere, clockwise in sh, rotation deflection is a result of the coriolis effect. Coriolis effect: phenomenon that causes water and air to curve as they travel across or above the earth"s surface, earth rotates at an effectively constant angular velocity, different latitudes have different linear speeds, equator: ca. Influences big, slow moving things (global weather patterns and storms) not small fast things (toilet & sink water draining) Hurricane season: late summer/early fall, on land, kighest temperatures occur ca. 4-6 weeks after summer solstice (june 21: oceans have higher heat capacity, reach highest temperature ca. 3 months after the summer solstice: northern hemisphere: july october, southern hemisphere: january april. Tropical cyclone berguitta: formed into a tropical cyclone on jan 14, 2018, sustained wind speed 157km/h on jan 16 2018 (cat.
