what is meteorology? study of the Earth's atmosphere
T or F? weather forecasting is a True
subset of meteorology
why is meteorology a non-perfect - a non perfect science because it's always changing
science?
what is weather? the current state of the atmosphere
what is climate? collective state of the Earth's atmosphere over a long (30 years) period of
time
what defines an atmosphere? gasses that surround the Earth and other planets
weather is produced 4-10
approximately _______ miles up
T or F? composition of the false. composition is NOT constant
atmosphere is constant from
place to place and time to time
- 340 BC
- father of meteorology
- wrote Meteorologica (a document on weather and how we
observe clouds in the atmosphere)
Aristotle
- Largely incorrect; technology corrected him
- mostly theoretical/basic ideas
- developed the first writings and documents of weather
what does a thermometer measure? - measures temperature
who invented the first - invented by Galileo (1593)
thermometer?
how does a thermometer work? - expansion and contraction of liquid on an indexed scale
how is the thermometer - maximum measured with mercury
maximum/minimum measured?
- minimum measured with alcohol
what does a barometer measure? - measures pressure
who invented the first - invented by Torricelli (1643)
barometer?
, what does a hygrometer measure? - measures moisture
who invented the first - invented by Davinci (1660)
hygrometer?
why are the 1600's significant? time of many many advancements in meteorological technology
what does an anemometer - measures wind speed
measure? who invented the first - invented by Robinson (1864)
anemometer (4 cup
anemometer)?
- invented 1843
when was the telegraph invented - first long distance communication
and why is it significant to - Changed the world by giving us the ability to communicate more;
weather? made spreading information about weather to different areas
possible
who developed the air mass - developed by Norwegians 1920's
frontal theory and when did the - not used in US until 1940's
U.S begin to use it?
1. air temperature - hotness or coldness of the air dependent on motion of
molecules
2. humidity - the moisture in the air
3. clouds
what are the 8 elements of weather? 4. precipitation- snow, rainfall, what a weather radar detects
5. wind direction
6. wind speed - gusts of air molecules
7. visibility - the ability to see in the sky depending on the weather
8. air pressure - weight of air
automated systems make this visibility
element decreasingly important
the most abstract element of air pressure
weather
T or F? the wind direction is true
always stated as where the
wind is coming FROM
what are clouds called "mother - tell us a lot about what is going on in the atmosphere
nature's signature"?
- invented 1940's
when were upper air balloons - Used in WWII to enable accurate action planning in the air
(rawinsonde or radiosonde) - first time people needed to calculate atmospheric conditions ABOVE surface
developed and what were they
