compare the weather of a typical warm front with that of a typical cold front - CORRECT ANSWER ✔✔warm air reaches a territory with cold air is a warm front. dense cold air reaching a moving into the area that is filled with warm air is known as a cold front. Friction makes the surface cold front to become slower than it's aloft position. the relative locations of the neighboring air masses steepen the cold front as they start moving. list 2 reasons why cold- front weather is usually more severe than warm-front weather - CORRECT ANSWER ✔✔-cold fronts are opposite of warm fronts. cold air actively intrudes on the region occupied by warm air. when air behind a cold front move over the warm surface radiation are emitted from the earth that can heat the air to produce shallow convection. cold type fronts produce thunderstorms. -cold fronts are steeper as compared to warm fronts, therefore more violent as compared to warm fronts in what way are drylines different from warm and cold fronts - CORRECT ANSWER ✔✔cold fronts approaches generally from the west to northwest. slope of cold fronts is steeper than warm fronts, therefore cold fronts are violent. the slope of the warm front is gradual. warm fronts are usually associated with mT air that enters the US from the gulf of mexico. drylines can be identified by comparing the dew point temperatures of the CT air west of the boundary and the dew points of the mT air mass of the east

describe the surface circulation of a midlatitude cyclone in the northern hemisphere - CORRECT ANSWER ✔✔midlatitude cyclone refers to the cyclones occurring over the area of North America, and approximately the area between southern Alaska and Florida. The mid latitude cyclones are the important weather producer over this region. briefly describe the weather associated with the passage of a mature midlatitude cyclone when the center of low pressure is located about 200 to 300 kilometers north of your location - CORRECT ANSWER ✔✔takes two or more days to pass a region. Cirrus clouds are the first sign of the approaching cyclone. Clouds get lower and thicker as a warm front approaches. precipitation and temperature rates increase and winds change from easterly to southeasterly as warm front comes. Once warm front passes, area behind would be mT. Temperature increases after passage and warm conditions are replaced by gusty winds and precipitation generated from cold front. Severe weather occurs after with heavy precipitation with expectation of hail or tornado. Warm flow is replaced by cold winds and temperature decreased. cloudless blue sky until another cyclone happens what winter weather is expected with the passage of a mature midlatitude cyclone when the center of low pressure passes about 100 to 200 kilometers south of a city near Great Lakes? - CORRECT ANSWER

briefly describe the basis of numerical weather prediction - CORRECT ANSWER ✔✔numerical weather prediction is the technique used to forecast weather using mathematical models designed to represent atmospheric processes. numerical prediction means behavior of atmospheric gases governed by use of physical principles of laws expressed in the form of mathematical equations. The future state of the atmosphere derived from the current state can be predicted by using numerical analysis. These equations interpret the terms of weather like temp, moisture, cloud cover, and wind. Computer applications are used to implement these tasks. If it is snowing today, what weather might be predicted for tomorrow if the persistence forecasting method is employed? - CORRECT ANSWER ✔✔if it is snowing at a particular region it might be reasonable to assume that it will be snowing few hours or even for a few days what is the technique that predicts the weather based on average weather statistics accumulated over many years? - CORRECT ANSWER ✔✔climatology is the technique forecasters use to predict the weather based on the weather statics which is accumulated over many years. how do satellites help identify clouds that are likely to produce precipitation? - CORRECT ANSWER ✔✔geostationary operation environmental satellites are equipped with instruments that detect

sunlight reflected from earth producing visible light images. Infrared images are obtained from radiation emitted from objects and when compares to visible images are esp useful in determining which clouds are most likely to produce precipitation and stormy conditions. what advantages do infrared images have over visible light images? Name one disadvantage - CORRECT ANSWER ✔✔infrared imaging techniques are used to monitor the weather in both day and night or 24 hrs a day. But visible imaging techniques are used to monitor the weather in daylight only. An advantage of visible images is their resolution, which makes detection of similar features possible. what weather phenomenon is the lifting index useful at predicting? - CORRECT ANSWER ✔✔severe weather occurences describe how abundant cloud cover affects minimum and maximum temperature forecasts - CORRECT ANSWER ✔✔overnight abundant clouds absorb heat radiation and radiate back all the longer wavelength radiations. longer wavelength conditions correspond to infrared conditions such as heat radiations. This will cause and increase in temperature on day timings, which is higher than the day that has no clouds in the evening.

Same occurs near the sea. unequal heating and same process repeated. during what seasons and at what time of day is air- mass thunderstorm activity greatest? why? - CORRECT ANSWER ✔✔late spring early summer because warm humid air is prerequisite for air mass thunderstorm activity. Around mid afternoon is when surface temperature is the highest summarize the three stages of air- mass thunderstorm - CORRECT ANSWER ✔✔Cumulus stage is a primary stage of the formation of the cumulonimbus. In this stage, updraft dominates. Mature stage is where heavy rain occurs, some hailing and stage updraft and downdraft occurs. Dissipating stage is which milder rain occurs. Downdraft main feature and entrainment causes evaporation what is a gust front? - CORRECT ANSWER ✔✔The fronts of the cold downdraft which confront with the warmer air of the surrounding atmosphere how is thunder produced? - CORRECT ANSWER ✔✔due to high temperature air heated quickly, it expands explosive and produces sound wave. Occurs simultaneously with lighting.

what makes the rotating air column of a tornado visible? - CORRECT ANSWER ✔✔due to dust and debris picked up from the earth surface when is "tornado season"? why does it occur at this time? - CORRECT ANSWER ✔✔april to june, spring. Occurs all the time, because in some months it reaches it peak. in what direction do the majority of tornadoes move - CORRECT ANSWER ✔✔they move from SW to NE, or w to e because tornadoes occur slightly ahead of a cold front in zone of sw winds and move to NE distinguish between a tornado watch and a tornado warning - CORRECT ANSWER ✔✔Tornado watches alert people about upcoming tornadoes in a given area and time. Tornado warning is issued by the National Weather Service after the tornado has happened. warns about possibility of destruction what advantages does doppler radar have over conventional radar? - CORRECT ANSWER ✔✔doppler radar improved ability to track thunderstorm and issue based on their potential to produce tornadoes, whereas conventional radar works by transmitting short pulses of electromagnetic energy. Doppler radar can detect motion directly.

why does the intensity of a hurricane diminish rapidly when the storm moves onto land? - CORRECT ANSWER ✔✔Source of warm and moist air is cut off. No latent heat is liberated, friction of land surface slows down wind speed and wind moves directly into center of low, eliminating large pressure differences what are the three broad categories of hurricane damage? Provide brief ex of each. - CORRECT ANSWER ✔✔Storm surge, wind damage, heavy rains and inland flooding. Storm surge is the rise of water level due to presence of storm. Wind damage is heavy forced winds that can damage larger area than storm surge, huge economic losses. Heavy rains may cause floods and might produce worse conditions than storm surge. List four tools that provide data used to track hurricanes and develop forecasts. - CORRECT ANSWER ✔✔satellites, aircraft reconnaissance, radar, data buoys. distinguish between a hurricane watch and a hurricane warning. - CORRECT ANSWER ✔✔Hurricane watch gives the possibility of hurricane occurrence with a defined coastal area. issued 48 hrs before predicted stormy winds. Hurricane warning tells us that the hurricane
