On the other hand, there are patterns in the weather map that are not clearly expressed but cause weather pain. It is believed that this may be related to “atmospheric tides”.
To explain the atmospheric tide in an easy-to-understand manner, it refers to the periodic changes in atmospheric pressure that occur due to the warming of the atmosphere by sunlight during the day and the cooling after sunset. It is a change in atmospheric pressure that fluctuates in a half-day cycle that repeats ups and downs.
This cycle may coincide with the cycle of human biological rhythm, which is a 1/1000 level change compared to the pressure fluctuation at the weather map level in (1), but it triggers weather pain. ..
This change is generally high around 9 and 21:00 and low around 3 and 15:00. Even when there is no low pressure or typhoon, the fluctuation range of atmospheric pressure seems to be about several hPa.
Previous studies have also shown that the risk of developing weather pain increases when the range of fluctuations in this ups and downs is greater than the average.
Finally, it is called micro-pressure fluctuation, which is a smaller change than the atmospheric tide mentioned earlier, and corresponds to a very small change of 1/10000 level compared to the pressure fluctuation at the weather map level in (1).
Examples of micro-pressure fluctuations occur when a cyclone approaches, when cumulonimbus clouds occur, and due to the effects of air currents over mountains.
The amount of change in atmospheric pressure due to micro-pressure fluctuations is 1 hPa or less, and the duration is as short as several minutes to several tens of minutes, but when it occurs, it often rushes multiple times a day.
The vibration is smaller and finer than the above two patterns, but it is thought that those who have a sensor sensitive to weather pain will be affected by such small changes.
As a result of many verifications with users so far, Weathernews has found that many people experience weather pain such as headaches and joint pains “when the change in atmospheric pressure deviates from the normal pattern”. increase.
In the weather pain forecast, the risk of developing weather pain can be displayed up to 6 days in advance with 4 ranks of “warning”, “caution”, “somewhat caution”, and “safety”, and changes can be confirmed.
