Short Responses for Garrison CH 8 and CH 9‚ Midterm‚ and part of AICE CH 7 Explain how wind‚ temperature‚ density‚ the Coriolis effect and the shape of the sea bed produce ocean currents and upwelling. Ocean currents are the continuous movement of ocean water driven by forces acting on the water‚ including: wind‚ waves‚ the Coriolis effect‚ temperature‚ salinity and tides. The contours of the sea bed influence the strength and direction of the current. Surface ocean currents are generally

To what extent can preparedness and planning mitigate the effects of tropical revolving storms? (40 marker) A tropical revolving storm is a term that covers hurricanes‚ tropical cyclones‚ typhoons and willy-willies. These intense low-pressure weather systems are associated with catastrophic wind speeds averaging at 120kmph and torrential rainfall. Tropical revolving storms are huge and extremely violent extending to about 500km in diameter. They occur in the tropics and the sub-tropics and form

the Atlantic Ocean occurs every year during a certain time period‚ usually referred to as the Atlantic hurricane season. The cyclones that occur during this period are usually tropical and are often referred to as depressions and hurricanes. This time period usually starts in June and ends in November. According to the seasons‚ the starting of the hurricanes and cyclones usually takes place in the end of summer‚ because this is the time period when there is the largest difference between the temperature

Abstract Scientific experimentation recorded in the Journal of Climate by Korty‚ Emanuel‚ and Bar‚ (2008) shows that the intensity‚ frequency‚ and lifetime of cyclones is directly related to the warming of the atmosphere‚ oceanic mixing‚ and the availability of a surplus of carbon dioxide. Cyclones are increasing in intensity but because of how few reach landfall and the lack of data related to landfall destruction no visible trends have been formed (Landsea‚ Pielke‚ & Emanuel‚ 2005).

Hurricanes and tornados are very different‚ yet also alike. In this essay I’ll be comparing the two to find which is more dangerous. A mobile‚ destructive vortex of violently rotating winds-the tornado‚ or a tropical cyclone with violent winds-the hurricane. Hurricanes and tornados are both made up of strong rotating winds. That’s just one of the things they have common. Both usually occur with violent storms and lot of rain. They also both form in circular patterns. Hurricanes and tornados are

“Queer Ecology” as my friends and family in the Philippines are being besieged by yet another tropical cyclone. Terrible because I feel guilty sitting cozily in front of my screen while halfway around the world hundreds of thousands of Filipinos who live in areas at risk of flash floods‚ landslides and storm surges are struggling to be evacuated as Ruby (the misleadingly sweet name the cyclone has been baptized with) maintains its Super Typhoon strength.

disaster is the effect of a natural hazard that effects the environment‚ and leads to financial‚ environmental and/or human losses. (Natural Disaster‚ 2009) The list of possible natural disasters includes: tropical storms‚ earthquakes‚ droughts‚ floods‚ cyclones and bush fires. Everyday around the world natural disasters take place and they shape the environment in which we live. Many countries have other natural disasters that strike them like tsunamis‚ tornadoes‚ volcanoes and many more. Droughts Droughts

Hurricanes come with different names depending where the location it occurred. Hurricane storms are called hurricanes‚ if they start over the Caribbean Sea‚ the Northeast Pacific Ocean and the North Atlantic Ocean; whereas‚ storms are called tropical cyclones‚ if they occur in the Indian Ocean or near Australia. There are two main factors that cause hurricane storms‚ which are warm water and moist‚ warm air. Hurricanes occur when the moist‚ warm air from the surface of the ocean rises and meets the
