Entering the rainy season in Okinawa Beware of weather pain such as headaches in the latter half of GW –Weathernews

It was announced today that the rainy season in Okinawa will start at 11:00 on the 4th (Wednesday), but for those who are suffering from weather pain, the unpleasant season is approaching.

According to the weather pain forecast announced by Weathernews, the rank of the weather pain forecast is from “Caution” to “Caution” from the latter half of GW to the beginning of the week.

I am worried regarding sudden illness due to weather pain such as headache and dizziness. If you are taking medicine for countermeasures, be prepared in advance.

The Baiu front stagnates over the South Sea

The Baiu front will continue to stagnate over the South Sea, and it is expected that rainy weather will continue in the Nansei Islands. Please be careful regarding your physical condition as it will be hot and humid.

Clouds are expected to spread easily in the latter half of Golden Week in eastern and western Japan, where sunny and comfortable weather continued. Also, since it will be easier to rain until the end of Golden Week, it is expected that the change in atmospheric pressure will be large, and the rank of weather pain will be more “warning”, and it seems that it will be the beginning of the Tsurai week for those with weather pain.

It’s still a time when we can’t think of the heat, so we can tolerate the temperature changes during this time. Please be aware that stress on your body is likely to accumulate.

“Caution” and “Slightly caution” will continue in the future

“Atmospheric pressure” is the key to weather pain

It is said that not only changes in the weather such as sunny and rainy weather, but also temperature, humidity, and atmospheric pressure are greatly related.

Especially with regard to temperature and humidity, you can feel changes in daily life such as “hot / cold” and “wet / dry”, but you cannot easily feel the changes in atmospheric pressure.

Weathernews Weather Pain Forecast builds a weather pain prediction logic focusing on changes in atmospheric pressure that are difficult to feel on the skin, even among the causative weather factors.

(2) Atmospheric pressure ups and downs that repeat twice a day at almost fixed times (atmospheric tide)

On the other hand, there are patterns in the weather map that are not clearly represented 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 following 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 regarding 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.

(3) Small periodic pressure fluctuations

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.
