a. If the winds are moving at the same rate from lower to higher. Pressure increases speed increases as winds continue to move from higher to lower pressures, but are moving without a “boost” from the Coriolis effect.…
* In most places tides are mixed. Because of the diurnal contribution, there is a difference in height (the daily inequality) between the two high tides in a given day.…
Hurricanes get their energy from low pressure zones in the tropical latitudes. Cooler waters or a change in wind speed or direction are some factors that weaken hurricanes. Hurricanes grow in strength over warm waters because there is more moisture in the air which helps cloud formation, which in turn strengthen the storms. So with cooler water there would be less moisture in the air which in turn would slow the hurricane down. A change in wind direction or speed would cause a mixing of the drier air into…
Ocean waves are caused by many different factors. Usually waves are created by the wind; the wind transfers its energy to the water, through friction between the air molecules and the water molecules. The stronger the winds, the stronger the waves. Water waves usually do not go horizontally, they only move up and down. Some factors that also cause waves are tsunamis, earthquakes, and hurricanes. Surprisingly, wind speeds, the distance over which the winds blow, and the time that the winds are in contact with the water all determine the height and speed of the wave. Waves can travel thousands of miles from their source of “origin”. But it’s not the water moving, it’s the energy. As a wave approaches shore, friction between the bottom of the wave and the…
h. As wind blows over the surface, it creates pressure and stress. Energy imparted by the wind increases the height, length, and speed of the wave. When wave speed equals wind speed, neither wave length or wave height can change.…
The landforms surrounding Coffs Harbour influences the rainfall greatly, The Great Dividing Range passes close to the area and the area has no major river systems. Due to these landforms higher rainfalls occurs east of coast due to the moist maritime air rising over the land. This leads to storms. The steep catchment is small in area and this causes flash flooding.…
Severe thunderstorms are aided in their development by: random turbulent eddies that lift small pockets of air, unequal surface heating, uplift provided by features of the terrain (such as along mountain barriers, small hills, and gentle rises), diverging upper-level winds interacting with converging surface winds and rising air, and warm air rising along a frontal zone.…
Winds and currents move the surface of the water causing waves. The gravitational attraction of the moon causes the oceans to bulge in the direction of the moon. Another bulge occurs on the opposite side because the Earth is also being pulled toward the moon and away from the water on the far side. Ocean levels fluctuate daily as the sun, the moon, and the earth interact. As the moon travels around the earth and as they, together, travel around the sun the combined gravitational forces cause the oceans to rise and fall.…

Natural Disasters have powerful forces , they affect the environment and the people because they destroy the areas where they hit .“The Great Galveston Hurricane of 1900 was the deadliest hurricane to ever hit the United States and caused between 8000 and 12000 deaths. The storm reached the Texas coast south of Galveston on September 8 as a Category 4 hurricane with a storm surge of 8 to 15 feet.” All Natural Disasters can be formed in different ways but one of the examples are that hurricanes can be formed by the warm and moist air…
The impacts can vary in severity due to a range of human and physical factors. Human factors include how urbanised the area affected is, as built up cities tend to have impermeable surfaces which increases run-off and therefore worsens the floods that occur. Torrential rain and flooding, along with storm surges and strong winds, are all hazards posed by tropical revolving storms. These hazards, similar to the storm, are inevitable and cannot be stopped from occurring but methods can take place to try and reduce the impacts. Physical factors are out of our control. The size of the storm affects how widespread the impacts are, as well as the duration of the storm and the intensity of the storm, also affecting certain areas. Preparation and preparedness are not the only methods that can be carried out. Monitoring and forecasting with the use of satellites and radar create computer models based on…

First, some background. Formation of hurricanes in the Atlantic Ocean occurs every year during a certain time period, usually referred to as the Atlantic hurricane season. The cyclones that occur during this period are usually tropical and are often referred to as depressions and hurricanes. This time period usually starts in June and ends in November. According to the seasons, the starting of the hurricanes and cyclones usually takes place in the end of summer, because this is the time period when there is the largest difference between the temperature of the sea and the land (Reider, 1999). Hurricanes basically originate due to the temperature difference between the land and the sea. The peak time of these tropical cyclones is during the September season. The month of May is usually inactive with regard to the tropical cyclones because the temperature difference is the least (Reider, 1999). The cyclones that form in the Atlantic Ocean in the end of the summer season are referred to as tropical cyclones because they usually originate from tropical locations. One more fact that makes them different from normal cyclones is that their cores, or center of the large spiral, is warmer as compared to any other part of the spiral at any point of height. The spiral of the cyclone comprises of thunderstorm clouds that are ready to burst out, and hence when they move, they produce high, strong winds and heavy rain falls. A special characteristic of tropical cyclones is that they have extremely low atmospheric pressures. Some of the pressures of tropical cyclones are the least that have been recorded above the seas. Several factors have…
