|international |air |transport |to |ensure |safe |and |orderly |growth
What |is |WMO? |- |ANSWERS✔✔ |A |specialized |agency |of |the |united |nations. |For |meteorology |(weather
|and |climate) |operational |hydrology |and |related |geophysical |sciences
Who |makes |the |upper |air |forecasts? |- |ANSWERS✔✔ |Centres |(WAFC)
Who |makes |the |aerodrome |forecasts- |TAFor |and |Briefing |documents? |- |ANSWERS✔✔ |Meteorological
|offices |(MO) |(veðurstofan)
Who |makes |SIGMET |and |AIRMET? |- |ANSWERS✔✔ |Meteorological |watch |offices |(MWO) |(veðurstofan)
Who |makes |the |METAR, |SPECI |and |MET |reports? |- |ANSWERS✔✔ |Aeronautical |meteorological |stations
|(AMS) |(veðurstofan)
Who |gathers |information |on |volcanic |ash? |- |ANSWERS✔✔ |The |Volcanic |Ash |Advisory |Centres |(VAAC)
Who |gathers |information |on |tropical |cyclones? |- |ANSWERS✔✔ |Tropical |cyclone |advisory |centres
|(TCAC)
What |is |the |atmosphere? |- |ANSWERS✔✔ |The |spheroidal |gaseous |envelope |surrounding |a |heavenly
|body
,Below |how |many |km |does |the |composition |of |main |gases |not |vary |with |height |(except |for |ozone)? |-
|ANSWERS✔✔ |Below |60km
What |are |the |constituents |of |the |atmosphere? |- |ANSWERS✔✔ |Nitrogen=78%
Oxygen=21%
(main |gases)
and |then |trace |gases:
Argon=0,95%
Carbon |dioxide= |0,04%
What |are |important |characteristics |of |air? |- |ANSWERS✔✔ |Air |is |a |poor |conductor |and |it |acts |as |a
|fluid
Earths |atmosphere |varies |vertically |and |horizontally |in..... |- |ANSWERS✔✔ |Pressure, |temperature,
|density, |humidity
The |vertical |variation |of |temperature |(temperature |lapse |rate) |provides |basis |for |the |division |of |the
|atmosphere |into |distinctive |layers
How |is |the |structure |of |the |atmosphere? |- |ANSWERS✔✔ |1. |troposphere |0-11km
2. |stratosphere |11-50km
3. |Mesosphere |50-80km
4.Ionosphere |80-700km
5. |Exosphere |+700km
How |long |up |does |the |troposphere |extend? |- |ANSWERS✔✔ |Up |to |about |11 |km |height |(8-18 |km
|depending |on |location)
How |much |mass |does |the |troposphere |have |in |the |atmosphere? |- |ANSWERS✔✔ |It |contains |about
|75% |of |the |mass |in |the |atmosphere, |therefore |almost |all |of |the |weather
, How |is |the |temperature |in |the |troposphere? |- |ANSWERS✔✔ |It |decreases |from |the |surface |upwards,
|caused |by |expansion |of |the |air |(1,98°C/1000' |or |0,65°C/100m)
How |is |the |troposphere |at |the |poles, |at |the |mid-latitudes |and |at |the |equator? |- |ANSWERS✔✔ |At |the
|poles |it |is |up |to |8km |(26000ft) |and |is |up |to |-40°C, |at |the |mid |latitudes |it |is |up |to |11 |km |(36000ft) |and
|is |up |to |-55°C |and |then |at |the |equator |it |is |up |to |16km |(53000ft) |and |-75°C
What |is |the |tropopause? |- |ANSWERS✔✔ |It |is |a |transition |from |the |troposphere |to |the |stratosphere, |it
|is |defined |as |the |place |where |the |temperature |no |longer |reduces |with |increased |height
How |is |the |temperature |and |the |height |in |the |tropopause? |- |ANSWERS✔✔ |Temperature |ranges |from |-
40 |(polar) |to |-80 |(equator) |but |is |on |average |-56,5°C |at |11km, |height |is |from |8-10km |over |the |poles
|and |16-18 |km |over |the |equator
What |is |the |definition |of |WMO? |- |ANSWERS✔✔ |The |boundary |between |the |troposphere |and |the
|stratosphere, |where |an |abrupt |change |in |lapse |rate |usually |occurs. |It |is |defined |as |the |lowest |level |at
|which |the |lapse |rate |decreases |to |2°C/km |or |less |provided |that |the |average |lapse |rate |between |this
|level |and |all |higher |levels |within |2 |km |does |not |exceed |2°C/km
What |does |the |tropopause |height |usually |mark? |- |ANSWERS✔✔ |The |maximum |cloud |height, |the
|presence |of |jet |stream, |the |presence |of |CAT |(clear |air |turbulance |or |TURB) |and |the |maximum |wind
|speed
Altitude |of |the |tropopause |varies |with |temperature |and |therefore..... |- |ANSWERS✔✔ |Time |of |year,
|latitude |and |time |of |day
What |is |the |stratosphere |and |how |is |its |height |and |temperature? |- |ANSWERS✔✔ |It |is |11-50km, |the
|temperature |there |stops |decreasing |with |height |and |initially |remains |constant |up |to |20km.
Why |does |the |temperature |in |the |stratosphere |start |increasing |with |height? |- |ANSWERS✔✔ |Because
|of |the |ozone |layer |and |the |sun's |ultraviolet |radiation |is |absorbed |in |the |formation |of |ozone.
