Earth Science Review
Climates and Oceans-
1. With coastal climates, the locations are on the windward side, meaning the weather patterns move from the ocean to land, giving them mild summers and cool winters. This means that there isn’t a very large temperature range for coastal climates. Inland climates are more of the land heating and cooling, because they heat to high temperatures in the day and then cool a great amount at night. Also, the weather patterns are moving from land to water, creating warmer summers and colder winters. Elevation affects climate, because the higher the elevation, the more the temperature decreases. As latitude increases and you go closer toward the poles, temperature decreases. Leeward coasts have warmer summers and cooler winters, and the weather patterns go from land to water. Leeward coasts have mild summers, and cool winters, and the weather patterns go from the water toward land.
2. Land and water heat and cool differently because in the day time, land absorbs more heat, making the temperature increase quickly. Water on the other hand reflects most of the heat from the sun, making the temperature increase in the day much less than that of land. At night, land gives off more of the heat it absorbed in the day, making temperatures cool pretty quickly, with a greater decrease in temperature. Water cools not as quickly, with a smaller decrease in temperature from night to day. This is because the cool water on the top gets pushed down by warm water in the deeper parts.
3.
4. The thermocline upwells, because the thermocline is the transition layer between the surface layer and the deep ocean currents. The deeper, colder water rises from below the thermocline, and replaces the not-very nutrient rich surface water, with nutrient rich water from below.
5. In El Nino, warm waters of the western Pacific migrate eastward and reach the South American coast. The cool nutrient rich water normally found off the coast of Peru gets replaced with warm, non

    All currents in the northern hemisphere move in a clockwise direction, while in the southern hemisphere they move in an anti-clockwise direction. Suprisngly landmasses can be responsible for changing the course of a current. Differences in temperature and salinity are also responsible for the movement of ocean water. In the equatorial region, ocean water gets more heated than in the cold polar regions. This makes the water “light”. Water in the polar regions is cold and heavy, so it sinks and flows towards the equator. The light upper layers of water are thus forced to move towards the poles where they get cooled. Some effects are winds blowing. Winds blowing over a warm current can become warm, and at the same time, pick up moisture, as warm winds are able to retain more moisture. Therefore, the wind that reaches the land brings down the temperature and can cause heavy rain. The western coast of Europe for example, is one. Winds blow cold and dry air. They help to bring down the temperatures in places, which would have been much hotter. The California current which is cold, which flows along the western coast of the U.S, makes the region much cooler than other places in the west coast on…

    The Leeuwin Current

    The Leeuwin Current has important consequences on both the climate and marine biota off the coast of Western Australia. The first part of this essay will study these effects and introduce the concept of low nutrients, low salinity and high water clarity. The Leeuwin Current originates from tropical regions, making it relatively warm in addition to the distinctive lack of large-scale upwelling (http://www.per.marine.csiro.au/public/oceanography/regional/currents.html). Upwelling is the process by which subsurface waters flow upward and replace the water moving away (Skinner, et al, 1999). This process and other factors that cause the Leeuwin Current and its distinctive attributes will be analysed in later parts of this essay.…

    5. How do warm currents become heated? How do cool currents become cooled? Water is an enormously efficient heat-sink. Solar heat absorbed by bodies of water during the day, or in the summer, is released at night, or in winter. But the heat in the ocean is also circulating. Temperature & Salinity control the sinking of surface water to the deep ocean, which affects long-term climate change.…

    The areas near the Pacific Ocean are generally characterized by small temperature variations during the year, with cool foggy summers and mild rainy winters. Inland areas, especially those separated from the ocean by hills or mountains, have hotter summers and colder overnight temperatures during the winter (weather.gov). San Jose at the south end of the Bay averages fewer than 15 inches of rain annually, while Napa at the north end of the Bay averages over 30 inches and parts of the Santa Cruz…

    The rates of vertical recycling of water is extremely slow in oceans, water from bottom of ocean may take thousands of years to reach the surface of ocean again. There are some specific areas where water rises known as sites of upwelling and some sites where water descends mostly in areas of convergence of warm and cold currents in the Polar Regions.…

    Fresh H2O absorption happens along the surface of the sea. It is because of the inflow of the river as well the precipitation, lowering the amount of salinity. Also, increase in salinity happened by sea ice formation and by evaporation. Since the salinification and freshening happened in variation of place, salinity located at a specific place return the water’s upstream there. In considering subtropical latitude, evaporation in a high surface builds high amount of salinity close to the surface of the sea. On the other hand, in considering subpolar latitude, high amount of precipitation builds low salinity close to the surface of the sea. In the interior of the ocean, both low and high salinity are…

    The Sun, which drives the water cycle, heats water in oceans and seas. Water evaporates as water vapor into the air. Ice and snow can sublimate directly into water vapor. Evapotranspiration is water transpired from plants and evaporated from the soil. Rising air currents take the vapor up into the atmosphere where cooler temperatures cause it to condense into clouds. Air currents move water vapor around the globe, cloud particles collide, grow, and fall out of the upper atmospheric layers as precipitation. Some precipitation falls as snow or hail, sleet, and can accumulate as ice caps and glaciers, which can store frozen water for thousands of years. Most water falls back into the oceans or onto land as rain, where the water flows over the ground as surface runoff. A portion of runoff enters rivers in valleys in the landscape, with streamflow moving water towards the oceans. Runoff and groundwater are stored as freshwater in lakes. Not all runoff flows into…
