Unformatted text preview: Persistent Characteristics of Mid Latitude Climate • Strong seasonality of temperature and moisture • Moisture controlled by cyclonic storms • Frequency of repeat storms related to Subtropical jet stream path • Strength of storms related to cyclonic strength (how low is pressure) Prospects for Climate Change? • Global warming will change seasonality of temperature and rainfall – Warmer summers and milder winters – More summer moisture and less snow? • Changes is temperature will affect jet stream position and position of cyclones • Changes in temperature will affect cyclone pressures (make them lower and stronger?)...
