🔍 Key Concepts

• diurnal pressure variation refers to regular daily changes in atmospheric pressure linked to solar heating • Consider where solar heating is strongest and most consistent on Earth • Think about how latitude zones (tropics vs. polar vs. mid-latitudes) affect daily temperature and pressure cycles

💭 Think About

• Which region experiences the most regular, intense daily cycle of heating and cooling from the sun? • In which of these areas would you expect the atmosphere to respond most strongly each day to daytime warming and nighttime cooling? • How do calm, low-wind areas versus stormy, high-wind areas affect how clearly you can observe a regular daily pressure pattern?

✅ Before You Answer

• Identify which of the listed regions is closest to the equatorial/tropical belt with strong solar input • Ask yourself where steady, light winds and calm conditions make small daily pressure changes easier to notice • Rule out regions known for frequent storms and strong frontal systems, where regular daily patterns are masked
