The daily recurring pattern of pressure...

🔍 Key Concepts

• Diurnal means something that happens on a daily cycle, usually linked to the sun’s heating and cooling of the atmosphere • How air pressure patterns differ between low latitudes (tropics) and higher latitudes • Difference between a broad-scale synoptic weather pattern and a small, regular daily pattern

💭 Think About

• Which option describes a regular, repeating daily cycle in pressure, rather than a one‑time reading or short‑term trend? • In the tropics, local heating from the sun creates a twice‑daily pressure oscillation; which term best fits that idea? • Which terms in the answers sound like they relate to large-scale weather systems versus local daily cycles?

✅ Before You Answer

• Identify which choices are about timing (daily / recurring) versus one‑off measurements • Separate the term that describes large-scale weather maps and frontal systems from the term that describes a local daily cycle • Make sure the option you pick explicitly connects pressure with a daily (diurnal) variation rather than temperature or lapse rate

The daily recurring pattern of pressure changes most noticeable in low latitudes is the __________.

pressure tendency

daily lapse reading

diurnal variation of pressure

synoptic pressure
