How does the weather affect our everyday lives
We will cover the different weather phenomenon that can affect and impact daily lives. Including fog, snow, lightning, tornadoes, and hurricanes.
Fog is a cloud with its base at or very near the ground. Fogs form when the air is cooled below its dew point or when enough water vapor is added to the air to cause saturation. Fogs formed by cooling include radiation fog, advection fog, and upslope fog, fogs formed by the addition of water vapor are steam fog and frontal fog. Driving in fog is considered to be the most dangerous weather hazard, especially if it is exceptionally dense fog or combined with other adverse weather conditions. Foggy conditions are the number one cause of large multi-car

(Near the Phillippines and the China Sea, hurricanes are called typhoons.) As the moisture evaporates it rises until enormous amounts of heated moist air are twisted high in the atmosphere. Name three conditions that must be present for a hurricane to form and explain why each condition is needed. The storm must be developing over warm water. The water must be at least 80 degrees Fahrenheit. The warm water provides the energy for increased evaporation of water from the ocean surface. Water vapor is the "fuel" for the hurricanes because it releases the "latent heat of condensation" when it condenses to form clouds and rain, warming the surrounding air. (This heat energy was absorbed by the water vapor when it was evaporated from the warm ocean surface, cooling the ocean in the process. Over the sea, a hurricane, cyclone or typhoon can cause the level to rise by several meters. This rise in water causes massive waves to hit the shores near the storm. Overland, the hurricanes do a lot of damage, with powerful winds blasting the landscape. Heavy rains from the hurricane's clouds also cause flooding. High Winds--This is the most important effect of a hurricane since it determines how powerful the storm is, and how much storm surge and damage it can cause. Winds in a hurricane can reach up to 200 mph. Tornadoes--This is probably the least thought of the effect of a hurricane, but they do occur. Hurricanes affect people's lives because they can do so much damage. Winds can damage houses, trees, and any outdoor property. If the hurricane doesn't destroy where people live then the major flooding after hurricanes might. When homes are destroyed, people may have to rebuild homes and
Tropical waters serve as the perfect breeding and growing place for a hurricane. Storms, such as Katrina, are able to develop because of the availability of water vapor over tropical oceans. This creates the ideal environment for the growth of a hurricane (Ahrens & Sampson, 2011).
All that which lives must grow and flourish, and so too did the storm grow and flourish. The ocean itself nourished the fledgling storm, for all hurricanes derive their energy from the evaporation of water from the ocean surface. The wind itself powered the hurricane, for all parents seek to raise their children above themselves. With such sustenance, the cyclone swiftly deepened (Longshore).
Hurricane Andrew also caused many short and long term effects on the ecosystem and local economies. Leading up to this storm, many prominent scientists believed that the hurricane would never make landfall, or if it did hit, would not cause any major damage. Due to this foolhardy belief held by the scientists, many civilians did not have any time to evacuate their homes and barely escaped with their loved ones and whatever small valuables or keepsakes they could grab. Regretfully, many families had to leave everything they had behind. Hurricane Andrew also damaged the livelihoods of many small shop owners and farms and caused long-term problems as well.
Hurricanes form over the ocean. Easterly waves, what hurricanes develop from, are long, narrow regions of low pressure which occur in ocean winds called trade winds. At first, these easterly waves can grow into something called, a tropical depression. A tropical depression occurs when winds are up to 31 mph. Then tropical depressions can be upgraded into a tropical storm if the winds reach speeds of 74 mph or less. Then finally a the storm can be bumped up into a hurricane if the winds reach 75 mph.
Hurricanes are born over the warm waters of tropical oceans and are formed by a low-pressure system caused by the heating of water. The heat causes the air to rise and form lower pressures in a feedback loop, making the hurricane stronger. Heavy rain results from a condensation of water and strong winds develop from warm air rushing to the eye of the hurricane. Essentially, greater storms and winds occur when the hurricane feeds of the rising temperature of the water. In addition, researchers studied disturbances and intense thunderstorms in the atmosphere over Western Africa and believe they are partly to blame for extreme hurricanes affecting the United States and Canada. While these are all the main ingredients of a perfectly natural process, they were not the primary causes of the damage done by Hurricane
Hurricane Katrina had a huge impact on the world and more specifically, New Orleans for there was substantial damage to the citizens property and more importantly their body and minds. The biggest impact Hurricane Katrina has was on the people of New Orleans. Having their homes destroyed or uninhabitable, thousands of New Orleans residents were forced to flee in the Superdome and t...
Mother Nature cannot be controlled and as humans we are forced to deal with various natural disasters. We have earth quakes, hurricanes, volcanoes, tornadoes and many other types of events that are weather driven. Many natural disasters affect our everyday lives and individuals may be forced to safe areas to protect themselves from potential danger. Natural disasters can also place a financial burden on people in affected communities. Hurricanes are strong storms that have been hitting the United States for as long as history can remember. Many hurricanes have hit the southeastern part of the United States the past 100 years. Some of these hurricanes have left little effect of society while others have scarred into the history
Crime rates went up, no one had a place to stay and water was polluted. The damage done by Katrina affected New Orleans and the other areas hit years after it struck. Restoration for the areas hit would need support from all across America and support groups across the country. No one was ready for this tragedy, or could ever predict the horrible outcome. Hurricanes are powerful and destructive storms that involve great rain and wind.
Hurricanes are one of the deadliest and most expensive natural disasters around. They are more common in areas of humid yet moist weather so they are very foreign to certain places. But to the places were hurricanes are the norm, the people take them extremely seriously because they kill people and ruin countless amounts of property. Hurricanes can attack and harm people in so many ways they can kill people, leave them homeless, it leaves children orphaned and disable them. On the west coast of the United States and other places hurricanes aren’t taken as seriously as other more common disasters, such as, earthquakes and volcanoes yet the hurricane can be a lot more damaging that both of those. Hurricanes are cyclones that develop over warm oceans and breed winds that blow yup to 74 miles per hour.
Hurricanes begin as tropical disturbances in warm ocean waters with temperatures of at least 80 degrees Fahrenheit. These low pressure systems are served by energy from the warm seas. If a storm reaches wind speeds of 38 miles an hour, it is 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.
For a hurricane to form, the ocean temperature must be warmer than twenty-six degrees Celsius, or eighty degrees Fahrenheit. Also, the air near the oceans surface must be filled with moisture. The seawater that is warmed by the heat from the sun evaporates to form vast storm clouds. As the warm air rises, the cooler air replaces it thus creating a wind. The rotation of the earth bends the wind inward causing it to rotate and spiral upward with a great amount of force. Around the Equator, the spin is the fastest. There, it can be faster than six hundred miles per hour.
The development of a tropical depression into a hurricane requires heat form the ocean’s surface. Warm water heats the air above the ocean which leads to a drop in air pressure. The drop in air pressure brings about strong winds which leads to more water vapor present, which makes a hurricane stronger because of the conviction at the storm’s center. This is the positive feedback loop that exists within a hurricane, making it stronger with each movement. For this reason, hurricanes that pass over cold water start to lose their momentum and power, leading to the downgrading their status to a tropical storm.
A Hurricane is a tropical storm with winds more than 74 miles per hour (mph). Hurricane wind damage is influenced by the duration and change of wind direction, amount of rainfall and how well land structures are build. Hurricanes are measure in five different categories and each category can produce different degree of damages. Category One Hurricane has sustained winds 74-95 mph. Category Two Hurricane has sustained winds of 96-110 mph with very strong winds that can produce widespread damage and extensive damage to power lines. Category Three Hurricane has sustained winds of 111-130 mph that will cause extensive damage with near total power loss that could last several days to weeks. Category Four Hurricane has sustained winds of 131-155 with extremely dangerous winds causing devastating damage. Finally, a category five hurricane has sustained winds greater than 155 mph. This is a catastrophic damage storm. Category five can have severe injury or death due to wind blown debris. A Category five hurricane can produce extensive power outages that will last for weeks to perhaps months. Therefor...
A tropical cyclone is a warm-core, low-pressure system producing high winds that spiral counter-clockwise (in the northern hemisphere) and inward, with the highest winds near the center of circulation. The large counter-clockwise and inward flow is characteristic of the nearly symmetric structure of tropical cyclones as they are comprised of rain bands spiraling toward the center. These warm-core storms typically form over the tropical and subtropical oceans and extract their energy from the heat content of the oceans. Tropical cyclones are organized into three main states, depending on their overall structure and maximum wind speed. The three main categories are: Tropical Depression • Closed low-pressure system • Winds must rotate fully around the closed low-pressure center • Maximum sustained winds of up to 39 mph Tropical Storm • Appear more circular than a Tropical Depression, indicating more organization • Clearly recognizable rotation • Maximum sustained winds from 39 to 73 mph Hurricane • Well-organized, often with a distinct eye • Pronounced, strong rotation • Maximum sustained winds greater than 73 mph • Large range in intensity is described by the Saffir-Simpson Scale
A hurricane is a type of natural disaster that can be harmful and destructive to anything in its way. Every year five to six hurricanes are formed, damaging and destroying people’s homes, landmarks, and anything in its path (“Hurricane”). Before a hurricane is developed it is known as a tropical storm. To be a tropical storm wind speed must be at least thirty eight miles per hour (“Hurricane”). Once wind speeds reaches seventy four miles an hour it can then be classified as hurricane (“Hurricane”). Large scale storms, like hurricanes have a variety of ways to measure the sev...
