February 2023 is a mild and cold month. According to BMKG monitoring, Indonesia weather in the next week there will be an increase in rain intensity due to the significant flaw of cold air masses from Asia and the active MJO. On a global scale, several indices still show significant values such as SOI (+12.2) and NINO (-0.56) which can support cloud growth in Indonesia. MJO is active in quadrant 3 (Indian Ocean), showing significant conditions especially for western Indonesia and will be active in quadrant 4 (Maritime Continent). Kelvin atmospheric wave activity is predicted to be active in parts of Kalimantan, South Sumatra and Central Sulawesi this weekend. Meanwhile, the Equator Rossby wave is also predicted to be active in parts of South Java in the next week. Thus, these factors support the potential for rain cloud growth in parts of Indonesia
