the higher the altitude the cooler the air becomes in general. The air cools, condenses and turns to minute water droplets at these higher altitudes to produce more moisture in the air which in turn leads to greater amounts of rainfall. The lower altitudes with the warmer air can hold more water vapour and less therefore condenses to form rainfall. The hypothesis is based solely on the basis that air becomes cooler with increasing altitude. HYPOTHESIS Aberporth weather
Ecological Footprint Bobby Chaiton Westfield State College Physical Geography Section 001 Carston Braun November 17, 2013 1. Describe the general time sequence between 24 and 30 August 2005 in terms of central air pressure and sustained wind-speed changes The wind speed changes when there is a difference in air pressure because of a function called the pressure gradient force. Simply put, the larger the difference in air pressure between two areas, the faster the air moves from the higher pressure to the lower pressure, just like a ball rolls down a steep hill faster than a more gently sloped one. As the central pressure of a hurricane increases, it causes the overall difference in pressure from the inside to the outside to become less, and thus the wind speed decreases in response
Hurricanes Hurricanes, also known as tropical cyclones, are low pressure storm systems that form on open water and feed on heat released when moist air rises. Hurricanes are recognized on radar by their distinct pin wheel shape. When hurricanes begin to take shape they are called a tropical storm. The word “tropical” is used because most of these storms are formed by the very warm water of the tropics. Hurricanes need the ocean’s water temperature to be about 80 degrees to a depth of about 150 feet.
El Nino – The phenomenon and its effect and its effects on southern Australia El Nino is a strange weather phenomenon that that is caused by the warming of the Pacific Ocean near the equator, off the coast of South America. This happens when the normal winds weaken which allows the warm water that is usually found in the western Pacific change
-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.
Discuss the impacts of storm events in the British Isles and evaluate responses the responses to them. (40 Marks) Storm events in the British Isles are caused by depressions which form out in the Atlantic Ocean and are brought to us mainly by the tropical maritime air mass moving north-east over the British Isles. A depression is a low pressure weather system formed where two different air masses meet along the polar front, this occurs rapidly as they are driven by prevailing westerly wind. They appear as masses of swirling clouds when viewed on satellite images, subsequently due to Coriolis effect resulting in an anticlockwise rotation in the northern hemisphere. The associated air masses of storms within the British Isles are Polar maritime and Tropical maritime.
Its bowl-like geography causes an entrapment of fog, air pollution and much of the horrible heat waves that are present during summer months. The San Joaquin Valley is hot and dry in summer with long, sunny days. Winters are moist and often blanketed with heavy fog. Due to San Joaquin Valley’s geography Tule fog is often a problem during the winter. Tule fog is a very thick fog that collects in parts of California during the rainy season of the late fall and winter.
Flash floods create deep canyons called arroyos and create depositional landforms such as alluvial fans. This relationship that deserts have with water makes deserts comparable to glacial landscapes because glacial landscapes are mainly formed by water. Advance and retreat is a huge factor in the creation
While one might ask how water erosion can be so prevalent in the desert, it is important to note that like many Australian deserts, the area receives a surprisingly high amount of rain, about 200-250 millimeters a year. ("Ayers Rock Facts," 2009) It is believed that the mountain chains that once included Ayers Rock were as large as the surrounding peaks. Now, there is just one remaining piece of this long lost chain. Wind and water took an enormous toll on the surface of the area. When one considers other major mountain chains, and is informed that they were once much larger, it is hard to grasp the concept due to the fact that the mountains still exist, and are fairly large in their current state.
This includes San Andreas Fault where a network of active faults underlies the LA region and San Francisco Bay Area. Secondly during El Nino years (every 4-7 years and lasting up to 2 years) there is a shift in the temperature of the Pacific Ocean resulting in warmer waters along the coast of South America.
