Atmospheric blocking

Atmospheric blocking occurs 20-40 times each year and usually lasts 8-11 days ... blocking can trigger dangerous conditions, such as a 2003 European that caused 40,000 deaths. Blocking usually results when a powerful, high-pressure area gets stuck in one place and ... fronts behind them are blocked. Lupo believes that heat sources, such as radiation, condensation, and surface heating and cooling, have a significant role in a blocking's onset and duration. Therefore, planetary warming could increase the frequency and impact of atmospheric blocking.
