background image Weather and Climate - GEOG 1250   Week 4    ● Hydrologic cycle (water cycle)  ○ Evaporation (liquid → vapor) 
○ Precipitation  
○ Condensation (vapor → liquid) 
○ Transpiration (from plants) 
○ Melting (ice → liquid) 
○ Sublimation (ice → vapor) 
○ Freezing (liquid → ice) 
○ Deposition (vapor → ice) 
  ● Ice ​ = Low temperature = Low energy  ● Liquid  ​= Medium temperature = High energy   ● Vapor  ​= High temperature = Highest energy     ● Sensible heat ​ = responsible for changes of temperature in water   ● Latent heat ​ = energy responsible for the phase change in water   ● Relative humidity ​ = how close the air is to saturation   ○ 70% RH = moist 
○ 100% RH = saturated (maximum threshold) 
○ 30% RH = dry 
● Mixing ratio ​ = how much water is present in the atmosphere   ○ High MR = High RH  ● Saturation mixing ratio ​ = Max amount of water that can evaporate at a given  temperature  ○ High temp. = High SMR / low temp. = low RH  ● Dew point ​ = the temperature the atmosphere has to cool down to in order to become  saturated   ● Dew point depression  ​= the difference between the temperature and the dew point  temperature    ○ Higher the DP depression = less saturation    ● The heat index ​ = combination of temperature and relative humidity  ○ The way our body is affected by the combo of the two → how it “feels”  ● Frost point ​ = temperature the atmosphere cools down saturation → falls below freezing    
Influences of temperature
​:  ● Latitude  ○ Cities closer to the equator (little change in temp.) 
○ Length of day variations (little change) 
○ Further away from equator (more change in temp. and daylight)
