PALEMBANG - Palembang City, South Sumatra, experienced the Madden Julian Oscillation phenomenon during July to early August. This weather phenomenon makes the air temperature cooler.

Head of Data and Information Section of Class I Climatology Station Palembang Nandang Pangaribowo said Palembang City was covered with rain clouds during July - early August so the weather became cold with temperatures of 22 degrees Celsius - 27 degrees Celsius and humidity 75 degrees Celsius - 95 degrees Celsius.

All areas in Palembang will receive rain with a thickness of 0 to 100 millimeters per hour. Although actually during this time span, it is still in the dry season.

This is due to the Madden Julian Oscillation (MJO) seasonal activity. So in that range, even though Palembang has entered the dry season, the weather is cold and accompanied by moderate rain.

"This phenomenon can occur at any time and does not have the potential to pose a danger," he said, quoted by Antara, Wednesday, July 14.

In climatology and geophysics, MJO is an intra-seasonal activity that occurs in the tropics. "It usually appears every 30 to 40 days in a year," he said.

This phenomenon can be recognized by the movement of convection activity or the movement of air, water in a vertical direction that moves eastward from the Indian Ocean to the Pacific Ocean.

The active MJO causes sea surface temperatures in the Indian Ocean region to decrease, resulting in increased rainfall in the western part of Indonesia.

Although in theory, it does not pose a potential disaster hazard, the community remains alert to flooding, especially for those who live in water areas or lowlands.
