Barometric pressure is the weight of air in an area, measured in inHg or hPa. Honolulu and San Diego have the smallest range of pressure variations in the US, while St. Paul and Charleston have the largest. Pressure is affected by factors such as altitude, temperature, and weather changes. Health problems such as joint pain, headaches, and ear problems can be related to pressure changes.
Barometric pressure is the weight of the air in a particular area, which is measured in inches of mercury (inHg) or hectopascals (hPa). Although the degree of air pressure in any place fluctuates all the time, some areas experience greater fluctuations than others. In the United States, the places with the smallest range of barometric pressure variations are Honolulu, Hawaii and San Diego, California. Because large pressure fluctuations, especially drops, are thought to cause or exacerbate a variety of health problems, many people prefer to live in areas with less change.
Largest and smallest range
Honolulu, Hawaii has the smallest range in the United States of change in barometric pressure, ranging from 29.34 to 30.32 inHg (993.56 to 1026.75 hPa). San Diego is the city with the smallest change range in the continental United States, with a mean range of about 29.37 to 30.53 inHg (994.58 to 1033.86 hPa). While places like Denver, Colorado may have low pressure consistently, they can also have a greater range of pressure variations. As for places with the greatest range of pressure variations, St. Paul, Alaska ranges from 27.35 to 30.86 inHg (926.18 to 1045.04 hPa). In the contiguous United States, Charleston, South Carolina has the largest range of variation, with a range of 27.64 to 30.85 inHg (936.00 to 1044.70 hPa).
Defined barometric pressure
Barometric pressure, also known as atmospheric pressure or atmospheric pressure, is the weight of air, measured by a barometer. Low pressure means there is less weight pushing down. It also indicates that the air is rising and cooling, which helps clouds form. High pressure means more weight and indicates sinking, warmer, less humid air. The pressure at higher altitudes is adjusted to what it would be at sea level to give a uniform reading.
Causes of pressure variations
The atmospheric pressure of an area is affected by several factors, including the gravity of the Earth in general and the temperature and altitude of specific areas. Places at higher elevations have less pressure than those at lower elevations, and hotter places have less pressure than colder ones. Weather changes also affect barometric pressure, especially thunderstorms, which are preceded by pressure drops. Solar winds, powerful streams of charged particles with magnetic fields that affect Earth’s atmosphere, are also thought to raise atmospheric pressure incrementally.
Related health problems
Changes in barometric pressure are thought to be related to a wide range of health problems, although most of the evidence is anecdotal. Many people with arthritis experience increased joint pain when the barometric pressure drops, such as before a storm, and people also tend to be more prone to general aches and pains when the barometric pressure drops. Many people also experience sinus congestion and headaches, which may be because pressure changes can cause air to become trapped in the sinuses. Many people also find changes in blood pressure to be a trigger for migraines, but this varies from person to person.
Some people may experience inner ear problems, such as ear pain and dizziness. This is especially common in people who have existing inner ear-related health problems, such as Meniere’s disease. A 2001 study by Bianchi-Demicheli et al. also found that pressure changes were linked to pelvic pain, miscarriages and vaginal bleeding, although the reason for the correlation is unclear.
