Stadard Sea Level Conditions - Answer- -1013.25 hPa -15'C Environmental Lapse Rate - Answer- -2'C per 1000ft -1 hPa per 30ft Atmospheric Pressure - Answer- - The force exerted by the weight of air in the atmosphere QNH - Answer- - Question Nil Height - The altimiter pressure setting that indicates altitude above mean sea level Area QNH - Answer- - The pressure setting issued by the air traffic services that applies to a large geographic area - Used when local QNH isnt available Air Masses - Answer- - Large bodies of air that have uniform tempurature, humidity, and pressure Cirrus - Answer- - Ci - Above 20,000 ft - Thin, wispy, ice crystral clouds Cirrostratus - Answer- - Cs - Above 20,000 ft - Thin, veil-like clouds covering the sky, often producing halos around the sun or moon Cirrocumulus - Answer- - Cc - Above 20,000 ft - Small, white, patchy clounds in a ripple pattern Altostratus - Answer- - As - 8,500 - 20,000 ft - Grey or bluish clouds coverning the sky, with a uniform appearance Altocumulus - Answer- -Ac - 8,500 - 20,000 ft - White or grey, patchy clouds with a wavy or bumpy appearance Stratus - Answer- - St - Below 8,500 - Uniform, grey, low-lying clouds Stratocumulus - Answer- - Sc - Below 8,500 - Low, lumpy clouds that appear in patches and can cover the whole sky Nimbostratus - Answer- - Ns - Below 8,500 - Think, dark, low clouds that can completely cover the whole sky Cumulus - Answer- - Cu - Below 8,500 - White, puffy clouds with flat bases Cumulonimbus - Answer- - Cb - Below 8,500 - Towering thunderstorm clouds with anvil shaped tops Isobars - Answer- Lines connecting points of equal atmospheric pressure High Pressure System - Answer- - Stable weather, clear skys, and light winds - Air moves outward and anticlockwise in the Southern Hemisphere Low Pressure System - Answer- - Unsettled weather, clouds, and rain - Air moves inwards and clockwise in the Southern Hemisphere Cold Fronts - Answer- - Marks the boundary where cold air pushes under warm air - Often brings rain, thunderstorms, and a drop in tempurature Warm Fronts - Answer- - Occur when warm air moves over cold air - Brings steady rain or drizzle and an increasein tempurature Trough - Answer- - Areas of low pressure extended out from a low pressure system - Brings instibility and rain Ridges - Answer- - Areas of higher pressure extended out from a high pressure system - Usually associated with fine, stable weather Col - Answer- - A region of relatively uniform pressure situated between two high pressure and two low pressure systems - Calm, light winds and nil weather Occluded Fronts - Answer- - Forms when a cold front catches up to a warm front - Thick clouds, moderate to heavy rain, and cool tempuratures Stable Atmosphere - Answer- When rising parcels of air cool faster than the surrounding air, causing it to sink back into position Unstable Atmosphere - Answer- Occurs when a parcel of air remains warmer than the surrounding air, causing it to continuously rise Neutral Atmosphere - Answer- Where an air parcel, once displaced vertically, neither rises further or returns back to its original position Absolute Humidity - Answer- The total mass of water vapor present in a given volume of air. Relative Humidity - Answer- The percentage of water vapour in the air compared to the maximum amount of water vapour the air can hold at a given tempurature Dew Point - Answer- The tempurature at which air becomes saturated Convection - Answer- Occurs with a parcel of air that becomes warmer than the environment Forced Assent - Answer- When a parcel of air is cooler than the environment and is forced to rise into the atmosphere
