Air Temperature Data Daily Mean Daily Range Monthly Mean Annual Range Normal

Temp. time series: temp at one place over time Salt Lake City Temperatures 2004 – Observed, Normals, Records

What Controls Temperatures at a Particular Location? • Latitude • Altitude • Nearby water (especially oceans) • Ocean currents • Position relative to prevaling winds • Mountains isolate water effects • Cloud cover (and albedo)
