Tsunamis are a series of very long waves generated by any rapid, large-scale disturbance of the sea. Most are generated by sea floor displacements from large undersea earthquakes.

The apparent temperature which describes the cooling effect on exposed skin by the combination of temperature and wind, expressed as the loss of body heat. Increased wind speed will accelerate the loss of body heat. A wind chill factor of 30 degrees or lower on exposed skin will result in frostbite in a short period of time.

Humidity is the amount of water vapor in the air and can be described in different ways.

The term that you'll hear most often to describe the humidity is relative humidity. This is the measurement of humidity that's hardest to understand.

The dew point temperature is the temperature to which the air must be cooled to reach saturation (assuming air pressure remains the same). The dew point is a direct measure of the amount of moisture present in the air, and directly affects how you feel... or in other words... measures the amount of humidity in the air. Remember, the temperature never drops below its dew point, but can drop to it. Generally, we start to feel some discomfort when the dew point gets to or just above 60 degrees

What is the difference between dew point and humidity and what effect does it have on the heat index?

Simple answer; warm air can hold more water than cold air

1 foot = 0.3048 meter
1 international nautical mile = 1.1508 statute miles
= 1.852 kilometers = .99933 U.S nautical mile (obsolete)
1 latitude = 69.047 statute miles = 60 nautical miles
= 111.12 kilometers
For longitude the conversion is the same as latitude except the value is multiplied by the cosine of the latitude.

Eyewall replacement is a process that major hurricanes, especially powerful major hurricanes undertake when they try to reorganize, and get stronger. An outer eyewall develops around the original eyewall, and begins to sap the inner eyewall of its intensity and moisture, and thus become the dominant eyewall.

Wind shear is a term given to upper level winds that blow from west to east against a westward bound hurricane, which tears up the hurricane's clouds, and hinders tropical development.

Hurricanes travel in a westward direction because in the tropics and subtropics, the Bermuda high, Bermuda-Azores high, or the subtropical ridge is the primary steering feature in the Atlantic. Air rotates clockwise around a high pressure system, which creates an easterly, or southeasterly flow that pushes tropical storms and hurricanes to the west.
