“Hurricanes almost always form over ocean water warmer than about 80 degrees F. in a belt of generally east-to-west flow called the trade winds. … This warm water lies well within the belt of easterly winds, so almost all the storms that form there move away from the coast, toward the west.
Hurricanes in the North Atlantic Ocean initially go from East to West due to the prevailing winds, the Trade Winds. Why do they then turn Northward? The Coriolis effect deflects their motion northward. … People who have experienced hurricanes are usually more likely to take appropriate action than those who have not.
The storm surge exists on the dirty side because winds spin around the storm counterclockwise, meaning the wind in this sector blows onshore, pushing water onto land. Typically, the faster the wind speed and forward motion of the hurricane, the higher the storm surge will be.
Observations show that no hurricanes form within 5 degrees latitude of the equator. People argue that the Coriolis force is too weak there to get air to rotate around a low pressure rather than flow from high to low pressure, which it does initially. If you can’t get the air to rotate you can’t get a storm.
Embedded within the global winds are large-scale high and low-pressure systems. The clockwise rotation (in the Northern Hemisphere) of air associated with high-pressure systems often cause hurricanes to stray from their initially east-to-west movement and curve northward.
The continent is rarely affected by tropical cyclones, though most storms to hit the area are formed in the North Atlantic Ocean. Typically, strong upper level winds and its proximity to the equator prevents North Atlantic impacts. No tropical cyclone has ever affected the Pacific side of South America.
The Coriolis force is part of the reason that hurricanes in the Northern Hemisphere rotate counterclockwise. … The Earth does spin however, and in the mid-latitudes, the Coriolis force causes the wind—and other things—to veer to the right. It is responsible for the rotation of hurricanes.
The right side of a storm is often referred to as its “dirty side” or “the bad side” — either way, it’s not where you want to be. In general, it’s the storm’s more dangerous side. The “right side” of a storm is in relation to the direction it is moving, according to the National Oceanic and Atmospheric Administration.
The exact path of a storm can depend greatly on how far north or south the Bermuda High is at that time. And since the high is a weak system (oftentimes due to a trough in the jet stream), tropical hurricanes can recurve back toward the east, according to NOAA.
The Right Side of the StormAs a general rule of thumb, the hurricane’s right side (relative to the direction it is travelling) is the most dangerous part of the storm because of the additive effect of the hurricane wind speed and speed of the larger atmospheric flow (the steering winds).
Meteorologists often refer to the right side of a hurricane as the “dirty side” of the storm. … So, the wind to the right of the eye essentially has a tail wind, and blows harder (perhaps 110-120 mph) than the wind to the left of the eye, which is blowing against the storm’s movement (perhaps 80-90 mph).
Strongest winds ( and hurricane-induced tornadoes) are almost always found in or near the right front (or forward) quadrant of the storm because the forward speed of the hurricane is added to the rotational wind speeds generated by the storm itself.
No known hurricane has ever crossed the equator. Hurricanes require the Coriolis force to develop and generally form at least 5° away from the equator since the Coriolis force is zero there.
“Tornadoes usually rotate in the same direction as the thunderstorm they’re associated with.” Therefore, if the warm winds blowing north from the equator meet cool upper-level winds out of the west, the tornado will rotate counterclockwise.
Since the 1850s, there have been no fewer than 54 hurricanes and 52 reported tropical storms that have hit the area. That’s because the nature of the state’s gulf often becomes a receptacle of sorts for eastern blowing winds. New Orleans is particularly susceptible due to its relatively low elevation.
If dry air finds a way in, it will quickly erode the whole system and weaken the storm.
…
Below are the top three factors that have a direct impact on the strength of tropical systems.
In fact, tropical cyclones — the general name for the storms called typhoons, hurricanes or cyclones in different parts of the world — always spin counterclockwise in the Northern Hemisphere, and spin in the opposite direction in the Southern Hemisphere.
Dakshayani was the first hurricane ever in the Antarctica Basin. … It became a Tropical Storm on December 23, and a Tropical Depression on December 25. It’s remains made landfall in the Antarctic Peninsula on December 26, before dissipating on December 27.
Currently, Hurricane Wilma is the strongest Atlantic hurricane ever recorded, after reaching an intensity of 882 mbar (hPa; 26.05 inHg) in October 2005; at the time, this also made Wilma the strongest tropical cyclone worldwide outside of the West Pacific, where seven tropical cyclones have been recorded to intensify …
Water temperatures in the Atlantic Ocean average about 80 degrees because of the warm air from the Gulf Stream. … The warmer the water, the better chance the storm becomes a strong hurricane. California lacks these warmer waters and is usually under 75 degrees, even around 60 degrees in the upper northwest.
For one to form, there needs to be warm ocean water and moist, humid air in the region. When humid air is flowing upward at a zone of low pressure over warm ocean water, the water is released from the air as creating the clouds of the storm. As it rises, the air in a hurricane rotates.
At the center of the storm is the low-pressure core, a region of relative calm that is often free of clouds and is known as the eye of the storm. In the high-rising wall of clouds that encircles the eye, the hurricane’s most ferocious wind and weather conditions are found.
Hurricanes start simply with the evaporation of warm seawater, which pumps water into the lower atmosphere. … Once they move over cold water or over land and lose touch with the hot water that powers them, these storms weaken and break apart.
A: When hurricanes make landfall, they can spawn tornadoes. The friction over land is much stronger than friction over water, where the hurricanes form. … The tornadoes spawned by hurricanes typically occur in the right front quadrant of the storm and usually within 12 hours after landfall.
Fortunately, hurricanes are rare in Hawaiʻi—the last major hurricane to hit the Islands was Hurricane ʻIniki in 1992, which caused $3.1 billion in damage and devastated the island of Kauaʻi; it killed six people. The most recent was Hurricane Lane, which peaked as a powerful Category 5 hurricane in August 2018.
Hurricanes can form in the Caribbean or the Gulf of Mexico, but late in the hurricane season more of them form near the Cape Verde Islands of Africa. ATLANTA — Ida is the latest storm in a very busy Atlantic hurricane season that has one 11Alive viewer asking questions about the formation of dangerous tropical systems.
So why doesn’t it typically rain in California during the summer months? “California is a Mediterranean climate,” said AccuWeather Founder and CEO Dr. … “There are seasonal rains in California; the rainy season starts in October and lasts until March. The rest of the year is dry in Southern California.”
