GradeBuddy is best used as a supplement to your own notes, not as a substitute.i. Cirrus: Curly or fibrous shape; high altitude cloud. ii. Stratus: Flat or layered shape. iii. Cumulus: Puffy and/or piled: Moderate uplift.iv. Nimbus: Produces precipitation.-Cumulonimbus:strong uplift (cold front). Often bring intense storms and towering clouds.-Nimbostratus: dull, often featureless like fog. Gentle uplift (warm front)v. Fog:ground-level stratus clouds. Forms when air temperature is very near dew point, and water vapor enters the air.II. Fronts: When air masses meet this is called a front.i. Cold Front: Steep slope: narrow band of frontal weather. Cold air mass movesinto warm air and warm air is abruptly lifted.-Weather with cold fronts: the temperature goes from warm to getting colder. Precipitation: intense thunderstorms.ii. Warm Front: Gentle uplift: wide band of frontal weather. The warm air mass is active. Weather: cool to sudden warmth. Precipitation: before the front there are showers, snow, sleet, and after; clear weather.iii. Occluded Front: When a cold front overtakes a warm front. Combination of both weather patterns.III. Mid-latitude Cyclone formation-Warm and cold fronts are connected in mid-latitude cyclones. Weather conditions are predictable. -Polar front: where most mid-latitude storms form. Storms form mainly in the west and mature as they move east.-Sometimes there are variations in tropospheric atmospheric pressure which changes and the fronts start spinning. -Cold fronts move faster than warm fronts and form occluded fronts.-Mid-latitude cyclones form in waves along the polar
