Snowacane and Hurricane

The snowstorm that we had is being called a snowacane in comparison to a hurricane. The storm that we had and a hurricane are very different. These two storms are formed differently too. A winter storm forms when a massive cold air that is full of precipitation moves south from Canada and warm air moves north from Gulf of Mexico. Where the two airs meet is called a front. If the cold air pushes away the warm air and advances it called a cold front. If the warm air overcomes the cold air and advances it is called a warm front. If both the air masses are stationary and neither one advances it is called a stationary front. When it is a cold front either one of these precipitations fall, rain, freezing rain, sleet, or snow falls. Precipitation is when the clouds are too heavy to hold the water that evaporated from the ocean. The water falls in the form of sleet, rain, freezing rain, or snow depending on what kind of front there is. In our case it was snow. Snow is formed when water vapor experiences the stage of deposition. Deposition is when water vapor changes directly into ice, without becoming a liquid first and then falls to ground. When snow falls continuously for a long period of time it is called a blizzard. A blizzard has very strong winds and severe snowfalls. There are three main factors to have a blizzard, cold air surface, moisture, and lift. Lift is when warm air rises over the cold air. As opposed to this, hurricanes form differently.
A hurricane is a gigantic storm that rotates counter-clockwise around an eye. The eye of the hurricane is the calmest part of the hurricane with good weather and slow winds. Also, a hurricane has very strong winds that can be as fast as 75 to 200 mph. A hurricane can form only over really warm ocean water that are 80 degrees Fahrenheit or warmer. Furthermore, the wind must be blowing in the same direction to force air upward. Then the wind has to flow above the storm allowing the air below to rise. Humid air that is rising makes the clouds of the storm. Lastly, the light winds from the outside steer the hurricane and let it grow. Even though, these two storms are formed differently they both are affected by the same thing. Changing Global Patterns. Global Patterns are long-term global climates changes that reach far around the globe and affect day-to-day weather.
These storms have another thing in common, they affect the community in a negative way. A snowstorm traps the people inside and causes all kinds of damage to the houses. Moreover, a snowstorm causes accidents on the road when the snow on the ground turns to ice. Also, the winds can be very strong and temperatures can be very low. Similarly, a hurricane can be just as worst depending on the winds and type. A hurricane can destroy forests, hurt people and animals, damage buildings, damage cars, and some hurricanes can destroy houses to an extent that the houses can't be fixed. These are the differences and similarities between a winter storm and hurricane.


A snow storm. A hurricane.
