Each event normally lasts 9-12 months they often starts in spring reaches its strongest point between December and January and appears to end around may of the next year. It frequently brings record rainfall to Peru, Chile and Ecuador. Southern Australia is often hit by drought and it also sees an increase in its temperatures. South east Australia heats up and because it is already dry due to drought there is a massive increase in the chance of bush fires. The other effects on Southern Australia are; lower rainfall, fewer cyclones, late and weak tropical monsoon and lower
California’s San Joaquin Valley is one of the states top agricultural regions. It is 240 miles long and bordered by many mountain ranges. Eight counties compromise the San Joaquin Valley. Much of the problem in Americans most productive farm region is simply a function of its unusual geography and climate. Its bowl-like geography causes an entrapment of fog, air pollution and much of the horrible heat waves that are present during summer months.
EXERCISE 10 PROBLEMS – PART I The following questions are based on the maps of average January sea-level temperatures (Figure 10-1) and average July sea-level temperatures (Figure 10-2): 1. Is the temperature contrast between the equator and the Arctic region greatest in the winter or summer? Temperature contrast between the equator and the Arctic region is greatest in the winter. Temperatures near or at the equator only change a few degrees between winter and summer, while the Arctic region changes up to 40 degrees between the seasons. 2.
This extreme pressure change makes the iso bars compact together creating fast moving winds and causing wind speeds to increase to even out the air pressure. 3. Describe the changes in central pressure and sustained wind speed between 29 and 30 August 2005? The air pressure from august 29th to august 30th changed from 904mbars to 985 mbars. While the air pressure increased the winds decrease as iso bars spread apart and wind is no longer moving at an abrupt pace.
("Geology," 2008) It resulted in the folding of the area and shortened the north/south length of the area by about 8.7 miles. (Jaritz, 2008) “Kata Tjuta, near the end line of this bulldozing movement, was tilted only by15 degrees. But Uluru was rotated and almost tipped over at a steep angle close to 90 degrees.” (Jaritz, 2008) The near vertical sediment layers evident within the formation of Ayers Rock are due to this major earth movement. The continuing formation of Ayers Rock occurred slowly after the Alice Springs Orogeny. About 65 million year ago, the climate of the area had become extremely wet, and this brought river sand, swamp deposits, and small traces of coal to the area.
D. Scholar Geography 1 November 11, 2012 Test Corrections #1 Question: Which atmospheric heating process involves the emission of energy from an object? Correct Answer: E) Radiation My Answer: D) Why it’s Wrong: Radiation is the right answer because it has much stronger. It’s stronger than transmission, scattering, reflection and absorption. A good example would be: if your wearing a black shirt out in the sun you would be much hotter than if you’re wearing a white shirt. The black shirt would also fade over time because the suns rays would eat up the shirt.
Theses surfaces have a higher thermal capacity than natural surfaces and are able to absorb large quantities of heat during the day and slowly release it during the night. This is the main contributor in the temperature difference between rural and urban areas. Given that most of the city is covered in these building material s there is bound to be a change in climatic characteristics. However there are other factors such as central heating, traffic fumes, factories, power station and the people
Most of the sixty-plus volcanoes that erupt each year are low risk, however a combination of factors can cause a volcano to be a serious hazard. The factors causing these variations will be explained in this essay. The first factor that must be considered is the viscosity of the magma. This can determine how powerful an eruption is and what shape the volcano eventually becomes. Viscosity can be affected by three main factors, Firstly, the higher the temperature, the lower the density of the magma, causing it to flow more easily.
The associated air masses of storms within the British Isles are Polar maritime and Tropical maritime. As these two bodies of air move towards each other the warmer, less dense air from the south rises above the colder, dense air from the north. Circulations of low pressure then develop at points where the air is rising vigorously, this then coincides with waves in the polar front and jet stream. As a consequence there is much unsettled weather including heavy rain, strong winds and a variety of stormy cumulus clouds form; all of which can have devastating impacts socio-economically for an area as well as on the environment. The storm of 1987 occurred on the 15th and 16th of October due to a depression forming within the Bay of Biscay and had disastrous effects on the south and south-east of the UK.
The word savanna stems from an Amerind term for plains which became Hispanicize after the Spanish Conquest. It is a transitional biome between those dominated by forests and those dominated by grasses. The Savanna biome is associated with climates having seasonal precipitation accompanied with a seasonal drought. A multitude variant, the parkland, is located in the drier portions of the humid continental climate. Savannas have warm temperature year round.
