Elements of Weather
Weather definition.
Day to day condition of the atmosphere e.g. rainfall.
What is weather forecasting?
Prediction about various aspects of the weather for the coming days.
Climate definition.
Average weather conditions of an area over a long period of time e.g. 35 years.
What is an air mass?
A body of air with similar moisture and temperature characteristics e.g. Polar Maritime
Name hurricane case study.
Irma
What is used to measure precipitation?
Rain gauge (mm)
What is the name given to the scientists who are trained to forecast weather?
Meteorologists
What do the line and bars represent on a Climate graph?
Line - Temp, Bar - rainfall.
What do the following mean: Polar, Maritime, Tropical, Continental?
Polar - cold, Maritime - wet, Tropical - warm, Continental - Dry
What was the date the hurricane became a tropical storm?
30th August 2017
What unit is air pressure measure in?
Millibars (mb)
On land, at sea and in the air.
What does it mean by the term 'Latitude'?
Name the 3 main characteristics of a depression in order?
Warm front, warm sector, cold front
What category was the hurricane?
5
Name the four main types of clouds.
Cirrus, stratus, cumulus and cumulonimbus
What are the limitations of weather forecasting?
Range and Accuracy
Explain 'Continentality'.
The impact that being away from the ocean has on temp. Inland - hotter in summer, colder in winter than coast.
Differences between an anticyclone and a depression in a synoptic chart and satellite images?
Depression - Anticlockwise, warm front, warm sector, cold front, isobars are close together, low pressure, clouds
Anticyclone - no clouds, no rain, isobars far apart, high pressure, no fronts
Give one impact on people from case study.
Deaths, no insurance, no resources etc
What does the Beaufort Scale measure and explain how it works?
Wind speed - through visual observations
Give 4 factors describing a Stevenson's screen.
Above ground, roof, away from buildings, slats, on grass surfaces, white, no shade
Explain the impact of of altitude on temperature.
Higher altitude, colder temperature (decrease 1C every 100m). Air is thinner, can't hold as much heat and atmosphere is heated from ground up
Why are conditions calm in an anticyclone?
Give one impact on property from case study
Cost, flooding, lack of power etc
