Week 10 Flashcards
What is the difference between weather and climate
Weather is the value of these properties for a specific day.
Climate is the expectation of these properties for a particular time of year.
Name some properties of weather
Temperature
Precipitation
Pressure
Humidity
Wind speed
What is a difference of climate and weather?
Climate isn’t chaotic, weather is
The chaos of weather averages out across the year to give expected values.
How much water vapour does the atmosphere hold?
1.26x10^16 kg at any one time
How do you calculate the resident timescale?
amount stored/rate of flux in and out of a store
What influences the amount of water vapour in the air?
Temperature
humidity/saturation
What is the relative humidity?
The percentage water vapour relative to the saturation pressure.
What is the dry bulb temperature?
the air temperature as measured by a dry thermometer
What is the wet bulb temperature?
The lowest temperature that can be obtained by a thermometer with water evaporating from the bulb
