1. An El Nino is an event where warmer waters are pushed to the region of Central America, caused by a shift in the atmospheric pressures that typically occur near the equator. Typically, the winds blow across the Pacific Ocean from East to west, moving from a high to a low-pressure system. These so called “trade winds” have an a effect on the water current that pushes the surface of the oceans to the west, thus creating an upwelling of cold water by Central America (Ahrens, 2014). In an El Nino scenario, the trade winds that typically push west in a strong manner cannot compensate for a strong shift in pressure. Thus, a high-pressure system in the western part of the Pacific Ocean pushes through the trade winds and flows air to the east. The new winds to the east reverse the flow of the upwelling and cold water and pushes the warmer waters over to Central America. Lastly, the normal precipitation that would occur in the west now occurs in Central America leading to potential flooding. In the cases of a very strong fluctuation of pressure changes, …show more content…
The earth rotates around the sun and this plays a profound effect on how the earth and its atmosphere circulate. Known as the Coriolis affect, the winds on earths surface as well as the winds a loft deflect to the right in the northern hemisphere and oppositely to the left in the southern hemisphere. Currently, with the earths rotation as it is now, as air apart of the Hadley cell cools and falls it deflects to become a northeastern wind, or what is commonly known as the North Eastern Trade winds (Ahrens, 2014). If the earth were to suddenly shift direction, all of these current circulations would revers. To expand, the trade winds mentioned before would actually be northwest trade winds in the northern hemisphere and southwest trade winds in the south. The polar winds would also change their current flow as well, changing from easterly to westerly winds in the north and vice versa in the southern
However, they play other roles as well. Due to the tilt of the Earth’s axis, some locations get more sunlight than others. Near the equator, sunlight can be seen for majority of the day. The climate ends up being very hot and dry for almost the entire year. The farther north, or south someone goes from the equator, the colder the climate becomes, and the less sunlight someone receives in a day.
The asthenosphere is making convection currents. Since the convection currents are always moving it causes the asthenosphere to move and bend because it is ductile. When the asthenosphere moves which is under the tectonic plates it will cause an earthquake or more specifically the Alaskan Way
Clockwise winds around the low pressure system blow the moist air over land. The relatively warm moist air meets the cold air coming down from Canada. The low increases the surrounding pressure differences which causes very different air masses to collide at faster speed. When the difference in temperature of air masses is large, so is the storms instability, turbulence and
The rainstorm that appeared late last week in the Southeast has now moved to the Carolinas; into the early hours on Monday tremendous amounts of rain continued to fall upon the city. Columbia, the capital the South Carolina received over 20 inches of rain, all from an unpredicted low pressure system (South Carolina Flood). A mass of residents and businesses in Columbia were engulfed by over a foot of rainfall overnight (East Coast Rain). “Sunday was the wettest day in the history of Columbia, according to the National Weather Service. The rainfall total at the Columbia Metropolitan Airport was 6.87 inches, the most rain that's ever fallen there in one day” (South Carolina Flood).
Hurricane Juan struck Halifax, Nova Scotia in 2003 creating the most damage in the history of Nova Scotia and killing 8 people and costing about $30 900 000 in damage. In order to prevent as much damage you first need to have a brief understanding of what causes hurricanes and how they work. After you know that you 're able to think of ways to be able to prevent damage and the lose of life. Even thought you can be the most prepared person ever and just waiting for a hurricane to come because you know you 're as ready as ever, most people probably won 't be just sitting and waiting for one to come so what meteorologists do is predict when another is likely to strike.
, changes in shape of the Earth’s orbit and its tilt can also affect climate as that determines the amount of sunlight that reaches the Earth. Similar to what is mentioned in the previous point; the tilt and position of the Earth’s axis affect temperature on very long timescales. This means that it take long for the position and the tilt of the Earth’s axis to change. Therefore, this also fails to explain the recent rapid warming of the
With an overall warm temperature, the weather is different then a location with a typically cold temperature. The United Eradyn has some dry seasons, but also has some wet seasons. The coast creates some winds near it but overall, not to windy. When storms clouds come across the planes there is nothing to slow it down. So in turn the plains, like the Eastern Plains, get heavy storms.
Superstorm Sandy Superstorm Sandy devastated almost all of the eastern seaboard and parts of Cuba. The hurricane started as a normal tropical storm over the warm waters near the equator (Pacific and Atlantic oceans). Then began to spin counterclockwise and form into a hurricane. The hurricane was given a category one rating on October 23, 2012.Even though the hurricane did not touch the Dominican Republic it still dumped twenty inches of rain in Hispaniola. Over fifty people died from flooding and mudslides.
Hurricanes can be powerful storms that form over ocean water in the tropics. Hurricane Sandy occurred in 2012 along the east coast along the United States. Hurricanes cause wide havoc to many coastal cities and inland cities and are very dangerous. First, there are many causes of hurricanes. Hurricanes are a storm with violent wind in particular a tropical cyclone in the tropics.
In major league baseball the late 80’s through early 2000’s can be described as the “Steroid Era”, in which many athletes were caught using performance-enhancing drugs that resulted in higher offensive performance, especially the number of home runs per season. As professional baseball is getting more and more competitive many athletes look to unethical ways to gain physical advantages over other players by taking steroids. For instance, Mark Mcgwire admitted to using steroids and had a phenomenal increase in offensive statistics in 1998 compared to other seasons. In his season of 1998 he broke the baseball single season home run record of 70 home runs, which was far more home runs he had hit compared to previous seasons when he wasn’t
The cooled air over the land moves in to take the place of the rising warm air over the water. That is how bodies of water can affect the
For cyclones in the Northern Hemisphere, winds blow counterclockwise and inward. Thus causes Earth’s surface winds to move into the center of the cyclone as air rises. The are going through the expansional cooling process and with that, the relative humidity will increase causing stormy weather to occur in that environment. Critical Thinking 7.
Cierra Greenidge Put to a choice! Jim Heynen story describes the beautiful and selflessness of humans making the right choice. The passage “What Happened during the Ice Storm” by Jim Heynen, has a very important idea and message it sends. The story has a very good theme to it and tells an important story. Throughout the story we see how the boys helped the pheasants out in the snow storm instead of leaving them out in freezing snow storm.
Haiti, a sovereign state located on the island of Hispaniola in the Greater Antilles archipelago of the Caribbean Sea, is one of the world 's poorest and least developed countries. Same to other developing countries, Haiti developed agriculture instead of industry. Furthermore, Haiti is a country which always happened flooding, droughts, hurricanes and other meteorological disasters that were mainly caused by climate change. These disasters did affect Haiti a lot in the aspect of economy change, diseases like malaria or cholera caused by tropical Cyclone hotspots and vulnerability and adaptive capability of this country. First of all, hurricanes and droughts caused by climate change produced a very big effect on economy of Haiti.
Second reason that cause hurricane is the global warming, you might didn 't know that the climate change can lead to the storm and another natural disaster. According to a research of George Tselioudis, a research scientist at NASA Goddard Institute for Space Studies (GISS) and Columbia University, global warming will increase and also decrease the temperature such as in the equator a temperature is hot and dry. On the other hand, temp in the pole
