It is incredibly easy for us to spot tropical storms when we are looking at satellite imagery. They have a distinctive circular shape and, as we have already mentioned, they spin. Because of the rotation of the Earth, tropical storms in the southern hemisphere spin clockwise and tropical storms in the northern hemisphere spin anticlockwise.
Then, what are the features of a tropical storm?
Tropical Storm Peter formed in the Atlantic early Sunday morning could acquire some subtropical or tropical characteristics by the middle of this week as it moves east and then south over warmer waters in the Atlantic. The NHC gives it a 30% chance.
This is what my research found. Tropical Storm: a tropical cyclone with maximum sustained wind speeds of at least 34 knots (39 miles per hour). When a tropical storm is identified, it formally receives a name (we’ll talk more about naming conventions later in the lesson). Tropical cyclones retain their tropical storm status as long as their maximum sustained winds remain.
They have a circular rotation and rotate counterclockwise in the Northern Hemisphere. The only difference between a tropical storm and a hurricane is wind speed. In fact, the technical difference between the two is just one mile per hour (mph) of maximum sustained winds.
How do tropical storms get their names?
Tropical cyclones and subtropical cyclones are named by various warning centers to simplify communication between forecasters and the general public regarding forecasts, watches and warnings. The names are intended to reduce confusion in the event of concurrent storms in the same basin. Once storms develop sustained wind speeds of more than 33 knots (61 km/h; 38 mph), names are generally.
One of the next things we asked ourselves was; when do tropical storms get their names?
Tropical storms are given names when they display a rotating circulation pattern and wind speeds reach 39 miles per hour (63 kilometers per hour).
When a storm reaches tropical storm status, winds of 39 mph or greater, the storm receives a name. When the storm weakens to a tropical depression, it will keep its name.
The tradition of naming storms started in 2015, when Storm Abigail was given the inaugural moniker in November.
How high can tropical storms be?
Tropical storms can quickly become very powerful with very high winds, heavy rain, and storm clouds that can reach nearly 60,000 ft above sea level – that’s around twice the cruising altitude of a commercial aircraft.
The most frequent answer is: a tropical storm has sustained winds from 39 to 74 miles per hour. A tropical storm will become a Category 1 hurricane once its winds reach 75 miles per hour, and a Category 2 hurricane once its winds reach 96 miles per hour. Category 3 hurricanes and above are considered major hurricanes.
How big is a typical hurricane?
Typical hurricanes are about 300 miles wide although they can vary considerably in size. The eye at a hurricane’s center is a relatively calm, clear area approximately 20-40 miles across.
The first condition is that ocean waters must be above 26 degrees Celsius (79 degrees Fahrenheit). Below this threshold temperature, hurricanes will not form or will weaken rapidly once they move over water below this threshold. Ocean temperatures in the tropical East Pacific and the tropical Atlantic routinely surpass this threshold.
Lets see if we can figure it out! Tropical storm-force winds can stretch out as far as 300 miles from center of a large hurricane. Frequently, the right side of a hurricane is the most dangerous in terms of storm surge, winds, and tornadoes.
