JAKARTA, NETRALNEWS.COM - The Indonesia Meteorology, Climatology, and Geophysics Agency (BMKG) has identified significant changes in atmospheric conditions since September 21, 2019. Changes in atmospheric conditions were in the form of weakening of dry air mass pressure from southern Indonesia.
This was stated by Deputy of Meteorology R Mulyono R Prabowo in a written statement received by Netralnews, on Monday (9/23/2019).
Mulyono said the weakening of the pressure of the dry air mass resulted in areas of moist air mass which previously tended to be in the north of Indonesia now tending to expand to the southern part of Indonesia. When viewed on a broader scale, low pressure areas in the Bay of Benggala have a significant influence on changes in wind patterns in Indonesian territory.
Since September 21, 2019, wind patterns in the territory of Indonesia are no longer dominated from the southeast to the south, but rather from the east. It is predicted that on 23 September 2019 the low pressure area in the Bay of Benggala will strengthen.
As a result, the convergence area and the slowing down of wind speed (convergence) are predicted to form longitudinal in East Kalimantan, Central Kalimantan, West Kalimantan, Riau Islands, Riau, Jambi, and Bangka Belitung. The existence of this convergence area increases the growth potential of rain clouds in Kalimantan and Sumatra.
The local scale atmosphere also shows conditions that are sufficient to support the formation of rain clouds. Atmospheric lability index in most regions of Kalimantan and Sumatra indicates sufficient atmospheric conditions to form rain clouds in the coming week.
BMKG predicts that in the coming week it will rain with heavy intensity potentially occurring in the following areas:
23-26 September 2019: Aceh, North Sumatra, West Sumatra, Riau, Riau Islands, Jambi, Bengkulu, South Sumatra, Bangka Belitung Islands, West Kalimantan, Central Kalimantan, North Maluku, West Papua, and Papua.
27-30 September 2019: Aceh, North Sumatra, West Sumatra, Riau, Jambi, Bangka Belitung Islands, West Kalimantan, Central Kalimantan, East Kalimantan, Central Sulawesi, West Sulawesi, Southeast Sulawesi, South Sulawesi, North Maluku, Maluku, West Papua, and Papua.
