The diurnal variation of pressure is not visible in the middle latitudes in winter because __________.

🔍 Key Concepts

• diurnal pressure variation and its typical cause • the difference between local daily cycles and large-scale weather systems • how mid-latitude winter storm tracks affect barometric pressure

💭 Think About

• Ask yourself what normally causes a small, regular twice‑daily pressure variation near the Earth’s surface and whether that mechanism changes much in winter. • Consider which process, among the options, actually operates strongly in middle latitudes during winter and could hide or overwhelm a subtle daily signal. • Decide which choices describe real atmospheric effects versus ones that sound scientific but are not typically used to explain daily pressure patterns.

✅ Before You Answer

• Verify which factor is primarily responsible for diurnal variation in pressure (solar heating vs. gravity vs. planetary rotation). • Check which answer choice involves synoptic-scale (large-scale) weather systems, such as fronts and traveling lows and highs, common in mid-latitude winters. • Eliminate any option that relies on a “critical temperature” or an unusual change in gravity or Coriolis force that is not part of standard meteorology explanations.

Question 1 of 27070

The diurnal variation of pressure is not visible in the middle latitudes in winter because __________.

the increased Coriolis force disperses the pressure variation

it is masked by the pressure changes of moving weather systems

the decreased gravitational effect from the sun causes the variation to fade

the decreased average temperature is less than the critical temperature
