    1. Climate Labs 13, 14, 15, 16

    2. Climate: Definition Page 143: A statistical summation of atmospheric processes over an extended period of time Mine: Average weather in a region, where “region” is an intersection of various controlling factors Climate, by this definition, can change over time in both cyclical and secular ways

    3. Climatic Classification Data USHCN, etc. Average Daily Temperature Average of Day’s Minimum & Maximum Temps MMTS (since mid-1980s) 55% Average Monthly Temperature Average of Daily Average Temps for Month Average Annual Temperature Average of 12 month averages Annual Temperature Range Warmest Monthly Avg – Coolest Monthly Avg

    4. Climatic Classification Data Normal Temperature Annual or Monthly Averages averaged over 30-year period Monthly Precipitation (total) Includes rain and rainfall equivalent Annual Precipitation Normal Precipitation Annual or Monthly Averages averaged over 30-year period

    5. Climographs – Lab 13 Display normal monthly average temperature and precipitation for a year

    6. (Synoptic) Controls on Climate Note: These can overlap to some degree A? LACEMOPS Latitude, Air masses and prevailing winds, Continentality & Coasts, Elevation, Mountain barriers, Ocean currents – warm or cold, Pressure cells, Storm tracks A = Anthropogenic effects?

    7. Anthropogenic Effects Are not “synoptic” since they’re trends over time Other trend effects include: Solar cycles, 11-year Earth’s position in space: Milankovic cycles (Core 5 text) Precession of Earth’s axis: 26,000 years Nutation – Earth’s axis wobbles: 41,000 years Change in eccentricity of orbit: 93,000 years Secular solar changes – very long term

    8. LACEMOPS More or less Lab 13
