Sustained winds of 12 to 19 knots are classified as "moderate breezes." In nautical terms, this wind speed can create some waves and is typically associated with pleasant sailing conditions.
Gale, aside from being a woman"s name,. is a catch all term for violent or forcible Maritime storms. Gale force winds- 35 knots and up- it varies ( Cyclonic used to be 65 Knots- nautical miles per hour here- and Upwards!) always with a nautical bent- cold Gales at Atlantic city- but not inland. Gale really refers to the strength of the wind and not any, essentially, precipitation, unlike squalls, water-spouts, etc.
There are many factors which are required to cause a hurricane. But the first is a low pressure core which creates a system of showers and thunderstorms. These storms move out over warm ocean water and the moisture feeds and strengthens them. As this group of storms intensifies and organizes, the Coriolis effect starts the air spinning in a counter clockwise direction if it is in the northern hemisphere or clockwise if it is in the southern hemisphere. When the circulation becomes closed the system is called a tropical depression. When sustained winds reach 39 mph the storm is called a tropical storm and is given a name. When sustained winds reach 74 mph the storm is called a hurricane.
Prevailing winds are winds that blow predominantly from one direction over a particular location. The name "prevailing" suggests that these winds are the most common or dominant direction of wind flow in a given region.
Hurricanes begin as tropical disturbances in warm ocean waters with surface temperatures of at least 80 degrees Fahrenheit. These low pressure systems are fed by energy from the warm seas. If a storm achieves wind speeds of 38 miles an hour, it becomes known as a tropical depression. A tropical depression becomes a tropical storm, and is given a name, when its sustained wind speeds top 39 miles an hour. When a storm's sustained wind speeds reach 74 miles an hour it becomes a hurricane and earns a category rating of 1 to 5 on the Saffir-Simpson scale.The Saffir-Simpson scale was developed in 1971 and until 2008 and Hurricane Ike, used to be a measure of both wind speed and storm surge. Hurricane Ike measured at a category 2 on the Saffir-Simpson scale, but it's storm surge at landfall was at a level to match a category 4 storm. It was felt that many may have underestimated the need to evacuate based on the storms category 2 rating so for the 2009 hurricane season the scale was revamped to measure only wind speed. The storm surge will now be estimated by location.The Saffir-Simpson Wind Scale:Category One Hurricane (Sustained winds 74-95 mph)Category Two Hurricane (Sustained winds 96-110 mph)Category Three Hurricane (Sustained winds 111-130 mph)Category Four Hurricane (Sustained winds 131-155 mph)Category Five Hurricane (Sustained winds greater than 155 mph)
The North!
A tropical storm is given a name when it becomes a tropical storm, with winds of at least 39 mph.
When it becomes a tropical storm, or in other words, when winds reach 39 mph.
It is given its name before in even becomes a hurricane. Storms are named when they reach tropical storm status. Roughly half of all tropical storms become hurricanes.
Tropical Wave--These are the most common of tropical disturbances with about 100 forming each season. They lack a closed circulation, which is when there are winds in every direction. Wind speeds are less than 20 knots, or 25 mph.Tropical Depression--A wave becomes a depression when there is a presence of a closed circulation, and sustained winds are 20 knots, or 25 mph. At this point, the system is still quite disorganized.Tropical Storm--A depression becomes a tropical storm when shower and thunderstorm activity moves over the closed circulation, and sustained winds reach at least 35 knots, or 39 mph. At this point, the system is capable of causing minimal damage.Hurricane--A tropical storm becomes a hurricane when the closed circulation becomes an eye, and sustained winds reach at least 65 knots, or 74 mph. At this point, the system is capable of causing significant damage.
A tropical depression becomes a tropical storm when sustained winds reach 39 mph or greater.

The Coriolis Effect. It's caused by the rotation of the earth.
There are many factors which are required to cause a hurricane. But the first is a low pressure core which creates a system of showers and thunderstorms. These storms move out over warm ocean water and the moisture feeds and strengthens them. As this group of storms intensifies and organizes, the Coriolis effect starts the air spinning in a counter clockwise direction if it is in the northern hemisphere or clockwise if it is in the southern hemisphere. When the circulation becomes closed the system is called a tropical depression. When sustained winds reach 39 mph the storm is called a tropical storm and is given a name. When sustained winds reach 74 mph the storm is called a hurricane.
