      • Yes, seasons can affect blood pressure. Some people with borderline high blood pressure have higher readings during winter. And their pressure can get high enough to need medicine to control it. They might be able to reduce the dosage when spring comes, or stop taking the medication once summer rolls around.

  2. As air warms it ascends, leading to low pressure at the surface. As air cools it descends, leading to high pressure at the surface. In general, low pressure leads to unsettled weather...

  3. Mar 4, 2019 · If you carefully compute the average atmospheric pressure in midwinter versus midsummer, you will likely find that the average pressure is very slightly lower in winter than it is in summer. What you'll also find is that the extremes of pressure are more likely to occur in winter rather than summer.

  4. The long-term-average pressure patterns vary with season, the Summer North Atlantic Oscillation index (SNAO) used here represents the strength of a spatial pattern of pressure variability...

  5. Feb 4, 2020 · Areas prone to low pressure do not have extreme diurnal (day versus night) nor extreme seasonal temperatures because the clouds present over such areas reflect incoming solar radiation back into the atmosphere. As a result, they cannot warm as much during the day (or in the summer), and at night, they act as a blanket, trapping heat below.

  6. Sep 13, 2024 · First, it is clear that sea-level pressure is dominated by closed high- and low-pressure centres, which are largely caused by differential surface heating between low and high latitudes and between continental and oceanic regions. High pressure tends to be amplified over the colder surface features.

  7. In summer, high pressure usually results in clear skies, gentle breezes and fine weather. In winter high pressure leads to clear skies and colder conditions. There is less wind as the isobars...
