A study published in the Journal of Geophysical Research indicates, the chances of heavy rain and strong winds of 20 percent higher on weekdays between Monday to Friday. While on weekends and holidays, chances to 20 percent lower.
The data is compiled based on weather observations along the east coast of America. Observations made in recent summers, when bad weather such as thunderstorms and tornadoes are more common than in other seasons.
Although the observations were made along the east coast, experts from Nasa Gorrard who conducted the study predicted the result would be the same when applied on the west coast. Likewise, when applied in other seasons, as well as in other parts of the world because of the trigger factor is human.
According to the study, humans are also triggered the increased chance of heavy rain and strong winds through the activities done. The flurry of man's higher on weekdays triggers the release of various chemical compounds that greatly affects the weather.
Various compounds were released in the form of aerosol particles or droplets in the air, which, among others, derived from the fumes of motor vehicles and industrial machinery. When human activity is reduced on weekends, the release of aerosols is also reduced so that the chances of bad weather come down.
"This is the first study that linked the release of man-made aerosols with a high chance of torrential rain and a tornado in the middle of the week," the researchers said as quoted from Dailymail, Tuesday (12/27/2011).
In addition to affecting the weather, the aerosol particles formed from combustion in motor vehicles and industrial machinery also affects health directly. In the short term can cause respiratory problems, while in the long run could lead to cancer and heart problems.
