b. what is the relationship between maximum wind speed and maximum pressure?

The intensity of a hurricane is closely related to its central pressure with the lower the pressure the more intense the storm and its maximum sustained winds.

['For example, if the wind speed is 70 mph, the wind pressure is 0.00256 x 702 = 12.5 psf.', 'An alternative to calculating wind pressure at a particular wind speed is to use the standard for various wind zones.']

Wind has two important characteristics—direction and speed. The direction of wind can be gauged using an instrument called the wind vane. It is also called a weather vane. Every wind vane has two parts, the front and the rear.

A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. ... A high pressure system has higher pressure at its center than the areas around it.

Damaging winds are classified as those exceeding 50-60 mph. ... Wind speeds can reach up to 100 mph and can produce a damage path extending for hundreds of miles.

The temperature gradient between places results in differences in air pressure and ultimately, wind. Wind speeds increase with a greater temperature difference. Winds re-distribute energy around the world.

Convection currents create wind, which is horizontally moving air. ... The pressure difference between two locations is called a pressure gradient, and the force that actually moves air as wind is called the pressure gradient force.

A severe typhoon has wind speeds of 85–104 kn (44–54 m/s; 98–120 mph; 157–193 km/h), while a super typhoon has winds of 100 kn (51 m/s; 120 mph; 190 km/h). In May 2015, PAGASA introduced the term Super Typhoon and used it for systems with winds greater than 120 kn (62 m/s; 140 mph; 220 km/h).

Relationship between surface air pressure and windspeeds The lowest pressure reading ever recorded for a hurricane (typhoon Tip, 1979) is 870 millibars (mb). However, most storms have an average pressure of 950 millibars. Wind speed in a hurricane is directly related to the surface pressure of the storm.

Air pressure, also called barometric pressure, indicates how the weight of the atmosphere above is shifting. A falling air pressure generally means an approaching storm in the next 12 to 24 hours. The farther the barometric pressure drops, the more intense the storm. Air pressure is measured with a barometer.

Manufacturers measure the maximum, or rated, capacity of their wind turbines to produce electric power in megawatts (MW). One MW is equivalent to one million watts. The production of power over time is measured in megawatt-hours (MWh) or kilowatt-hours (kWh) of energy. A kilowatt is one thousand watts.

This inverse relationship between the pressure and speed at a point in a fluid is called Bernoulli's principle. Bernoulli's principle: At points along a horizontal streamline, higher pressure regions have lower fluid speed and lower pressure regions have higher fluid speed.

Wind speed describes how fast the air is moving past a certain point. ... Wind direction describes the direction on a compass from which the wind emanates, for instance, from the North or from the West.

Wind energy is the kinetic energy of the moving air. It has the highest kinetic energy.

Wind turbines require: a minimum wind speed (generally 12-14 km/h) to begin turning and generate electricity. strong winds (50-60 km/h) to generate at full capacity. winds of less than 90 km/h; beyond that speed, the turbines must be stopped to avoid damage.

2. Explain how the Coriolis effect, friction, and pressure gradients affect wind direction. Wind is the product of pressure gradients established between high and low pressure systems. These systems are constantly moving and changing.
