Why “Blocking Patterns” Prolong Heat & Rain
US · Published Sep 20, 2025
• Blocking patterns are large-scale weather systems that stall or slow down the movement of other weather systems, leading to prolonged weather conditions.
• High-pressure blocking patterns can cause extended periods of heat by preventing cloud formation and precipitation, while low-pressure blocks can lead to prolonged rain and flooding.
• Climate change may be influencing the frequency and intensity of blocking patterns, potentially leading to more frequent and prolonged extreme weather events.
Blocking patterns cause prolonged heat and rain
Weather sometimes seems stuck, with days of relentless heat or unending rain. This is often due to 'blocking patterns.' These atmospheric roadblocks disrupt the typical flow of weather systems, leading to prolonged periods of the same weather conditions.
