The question states, “There are four weather fronts used by meteorologist. List the four types. Using the following data, determine which two fronts are described. What other characteristics about these two fronts could be added to the ones provided for you? Data Front A: (1) ahead of the front the air is warm and moist (2) a sudden temperature change has occurred and (3) a thunderstorm has formed along the front. Data Front B: (1) there is a gentle slope between two air masses (2) stratus clouds have formed and (3) there will be an increase in temperature when the front passes.” The four types are listed below: Cold Front Behind the front air is cold and dry, ahead of the front the air is usually warm and moist. The cold, dry (cP) air mass behind a cold front …show more content…
One of the cold masses overtakes the other mass and the parcel of warm, moist air becomes trapped between the two cold air masses. To answer the second part of the question, “determine which two fronts are described. What other characteristics about these two fronts could be added to the ones provided for you? Data Front A: (1) ahead of the front the air is warm and moist (2) a sudden temperature change has occurred and (3) a thunderstorm has formed along the front. Data Front B: (1) there is a gentle slope between two air masses (2) stratus clouds have formed and (3) there will be an increase in temperature when the front passes.” Date Front A is a Cold Front, and Data Front B is a Warm Front. “Ahead of the front the air is warm and moist” That points towards Cold Front, but the dead give away for me was the mention of a thunderstorm forming along the front. Which if I recall Cumulonimbus clouds are thunderstorm clouds. “There is a gentle slope between two air masses” That points towards Warm Front, but again the dead give away for me was the mention of Stratus clouds. Which are commonly formed along a Warm
Single cell showers are when a single moist convective cell develops in an air mass that is moderately unstable. When the up draught and the rain downdraught come together in the atmospheric column, the downdraught overtakes the up draught. There then becomes a change of wind speed with height of the up draught column becomes tilted forward. The cold downdraught overtakes the inflow of surface air, cutting off the up dr...
Climate and weather are similar, describing how the atmosphere behaves, the difference being the timescale (Conway, 2010). Weather is a short-term scale of temperature and precipitation, usually considering weeks or less (ibid). Climate, however, is a long term description of months or longer, describing different seasons and trends of temperature and precipitation. Climate of Vancouver is typically mild during the spring and summer and damp during the autumn and winter, and unlike other mountainous areas of British Columbia, it is not excessively cold or snowy (“Hello BC”, n.d.).
On the afternoon of Monday May 3, two air masses met over central Oklahoma. One of the air masses was warm, moist air traveling north from the Gulf of Mexico. The other was cold dry air moving west across the plains from the Rocky Mountains. This collision of air
As evening approached, several thunderstorms began to take on the characteristics of a supercell thunderstorm. Supercells, which are intense, broadly rotating thunderstorms, are the most v...
This investigation is using a range of temperature in order to find weather or not
The next type of thunderstorm is a multicell storm, which is nothing more than what the name implies multiple cells working together to create a storm front. Several of these updrafts and downdrafts work together in close proximity to create what is called a mu...
Image analyst professionals at the U.S. Weather Bureau also found that all cyclones (hurricanes, nor-easters, tornadoes, etc) are characterized by a very distinct vortex cloud pattern located in the center. Because of these mutual characteristics, large scale cloud and weather systems could be easily recognized and tracked for many days. TIROS I detected a storm off the coast of Madagascar and tracked this storm through its television cameras for five consecutive days! Yet another major discovery was that the weather fronts associated with mid-latitude storms are strikingly clear and easily identifiable on weather-satellite photographs.
An ordinary-single cell is the most common, but multicell and supercells are responsible for the severe thunderstorms. The ordinary single-cell thunderstorms are short lived with three stages: the cumulus, the mature, and the dissipating stages. In the last stage, it eliminates the upward supply of high humidity air needed to maintain a thunderstorm. On the other hand, multicell storms are composed of severe individual single-cell storms that can make storms last for several hours. There is dense, cold air of the downdraft that forms the gust front which forms new cells. Then, groups of these thunderstorms tend to join into larger systems referred to as mesoscale convective
In “A Brief Encounter with the Enemy” by Said Sayrafiezadeh, Luke, a pessimistic soldier, walks down memory lane as he travels the path to get to the hill during his last recon. He remembers appreciating nature, encountering and writing to Becky, the first time he’d shot a gun, and Christmas leave. Luke identifies the moment when he realizes that he had joined the army for the wrong reason, after crossing the bridge his team built in order to cross the valley, and at the same time dreading the return to his former office job. Boredom and nothingness destroy him mentally as he waits for enemies to appear. When the enemies finally appear, he shoots them down and goes home the next day. Sayrafiezadeh proposes that expectations don’t always equate

Thunderheads. The air begins swirling around the storm center, for the same reason that the air swirls around a tornado center. As this air swirls in over the sea surface, it soaks up more and more water vapor. At the storm center, this new supply of water vapor gets pulled into the thunderhead updrafts, releasing still more energy as the water vapor condenses. This makes the updrafts rise faster, pulling in even larger amounts of air and
Back in the days of Thomas Jefferson and George Washington, weather observations were recorded daily but not hourly or by the minute. Such repetition of data didn’t seem useful. After the telegraph was invented which enabled information about weather data to be transmitted across the country, they still reported only once a day. In contrast to today's virtual world of weather, making 24/7 use of climate data from satellites, buoys in the oceans, the ability to record worldwide temperatures, worldwide rainfall records, track wind speeds, pressure pulses of solar wind, carbon dioxide levels, tornadoes and hurricanes...etc (Harris, 2012).
Air is composed of molecules. Air is matter. It has mass and takes up space. Air is composed of different gases such as nitrogen, oxygen, carbon dioxide, water vapor, and other gases. Air molecules are in constant motion. As they move, they come in contact with surfaces. Air molecules push and press on the surfaces they contact. The amount of force per unit area that air molecules exert on a surface is called air pressure. (What is Air Pressure 6) Air pressure is caused by all of the air molecules in the Earth's atmosphere pressing down on the Earth's surfaces. We can measure air pressure to help us predict weather conditions around the world. Temperature also affects air pressure because air contracts when it cools and expands when it is heated. So if air above a region of Earth cools, it does not extend to as high an altitude as the surrounding air. In this case, its pressure at higher temperature is lower than in the surroundings even when the pressure at the surface is the same as in surrounding areas. Then air flows into the cooler region at high altitude, making the total weight of air above the region greater than in the surroundings. This is a "high". The cool air descends to the earth's surface. Near the surface, the falling air spreads out,
absorbed. This will cause the atmosphere and the earth?s temperature to warm. The warming of
