It refers to the appearance of colder than average sea surface temperatures in the central and East Equatorial Pacific. It may follow El Nino but it has occurred less frequently. They are both short term climatic changes and are amongst the most powerful phenomena on earth as they affect the climate over almost half of the earth. During a normal year, there is high air pressure off the coast of South America with descending air. In the western Pacific, there is low air pressure as warn, moist air rises, cools and condenses, forming rain clouds which give heavy convectional rainfall.
Most begin closer to the equator, starting as thunderstorms that move out over the warm, tropical ocean waters. The rotation of a hurricane is because of the Coriolis force, a natural phenomenon that causes fluids and objects to veer to the right of their destination in the Northern Hemisphere and to the left in the Southern Hemisphere. How they form In the Northern Hemisphere, winds deflect to the right. In the Southern Hemisphere, they deflect to the left. This wind deflection gets storms spinning.
-Areas near the sea are cooler in the summer because the sea takes a long time to heat up and so cools the land down. -The West of the UK gets warmer more than the east because of a warm ocean current coming from the South West called the North Atlantic drift. 4) PRESSURE: -Low-pressure weather systems have lots of rainfall because the air is rising and water vapour is condensing. High-pressure systems have dry weather because the air is falling. -Low pressure weather systems come from the west, so the west of the UK is wetter.
Houle (2007) found that trees flowered 2-6 days earlier in 2000 than they did in 1900, indicating that global warming is impacting the phenology of plants. This can affect plants by altering their growing seasons, which may have unknown impacts on the plants. Increased temperatures linked to global warming have also been associated with decreased frost resistance, which can lead to an increased amount of damage to trees’ buds (Bannister et al. 2005). Studying these factors is important because it will allow us to understand and predict the changes that will occur due to the evolving climate and
The differences in urban climates are due to several reasons. Urban heat island affect is known to heat urban areas, urban areas are generally much hotter than surrounding rural areas. As you move from city centres into nearby rural areas the temperature is known to drop by up to 10 degrees. Around half of the world’s population live in urban areas but this rate is expected to increase to 70% by 2030. Negative affects relating to urbanisation is becoming increasingly concerning especially as there is an increased number of people who are moving out of the rural area into the urban/suburban areas.
As temperatures of the world changes the temperatures in the water changes as well. If global warming occurs in the world’s air, it will also happen under water. Not all coral bleaching are the result in warm water, it can also occur during colder weather. In January 2010 there was an incident in off the Florida Keys. Due to the temperatures dropping down -6.7 degrees Celsius, (20 degrees Fahrenheit) which is lower than normal causing the result for the coral to start the bleaching process.
A tornado can last a few minutes; however a hurricane can last for a couple of weeks. Both of these storms are very dangerous and destructive. Hurricanes are tropical storms that are formed over tropical water. Hurricane season is from June 1 and last until November 30. Each year hurricanes are given names and is rated on a Category scale from zero to five.
Hurricanes in Florida are a real threat during the six-month long Atlantic hurricane season, which runs from June 1 until November 30. The peak of hurricane season occurs between mid-August and late October, when the waters in the equatorial Atlantic and Gulf of Mexico have warmed enough to help support the development of tropical waves. A common misconception in Florida is that there are parts of the state that do not get hurricanes. Since 1850, Florida’s coastline has been impacted by at least one hurricane. With its long coastline and location, Florida frequently finds itself in the path of these intense storms.
3). From my understanding is that higher sea surface temperatures have made the storm surge stronger, normally hurricanes come up to the coast and turn right back into the ocean, but as a consequence of the major meltdown of Arctic sea ice, there was a weather pattern preventing Sandy from taking that course, and steered it back into land. Recently, I heard on news that several climate scientists made some starting points. They said was that surface temperatures in the western Atlantic Ocean were remarkably high just ahead of the storm — in places, about five degrees
Latosol is a rich red colour from iron oxides deposits as the net down movement of water leaches silica deposits downwards leaving less soluble iron oxides. There is a long wet period (8 months of years) where soil moisture store is full, rivers often flood. Short dry season December to Jan where evapotransporation exceeds precipitation. The rainforest is one of the most diverse ecosystems with the highest net primary productivity of 2200kg per m2 of organic matter and over 300 species of trees per km2. Trees are hardwood, mahogany, teak, rosewood, balsa and Brazil nut and vegetation is divided up into layers (zones).
