Fenomena Atmosfer Jadi Penyebab Hujan Di Jabodetabek | REDAKSI PAGI (07/07/24)

Summary

Heavy rain since Saturday morning in Jakarta caused flooding in several areas, particularly in Duren Sawit, East Jakarta, and Kapuk Muara, North Jakarta. Floodwater reached up to 30 cm, disrupting daily activities and causing traffic issues. The flooding was worsened by blocked drainage systems. The BMKG (Meteorological, Climatological, and Geophysical Agency) explained that recent weather patterns were influenced by significant atmospheric dynamics, including the Madden-Julian Oscillation and warm sea surface temperatures. These factors caused intense rainfall, which is expected to continue with possible thunderstorms and strong winds in the coming days.

Takeaways

• 😀 Heavy rainfall has been affecting Jakarta since Saturday morning, causing floods in several areas, including Duren Sawit in East Jakarta and Kapuk Muara in North Jakarta.
• 😀 In Duren Sawit, the floodwater reached up to 30 cm, making certain roads impassable due to blocked drainage systems.
• 😀 The Jakarta administration is working to clear drainage systems to help the floodwaters subside more quickly.
• 😀 In Kapuk Muara, North Jakarta, floodwaters also reached 30 cm and began to recede by the evening, but the area remained affected.
• 😀 Many residents had to navigate the flooded streets, with some vehicles being pushed due to engine failures caused by the water.
• 😀 Hundreds of homes in 4 RTs in Kapuk Muara were inundated by the floodwaters.
• 😀 The cause of the heavy rainfall is attributed to significant atmospheric dynamics and changes in regional weather patterns, as explained by the BMKG (Meteorological, Climatological, and Geophysical Agency).
• 😀 The phenomenon is linked to the Madden-Julian Oscillation (MJO), which influences weather patterns and causes heavier-than-usual rainfall during the dry season.
• 😀 There are also signs of the equatorial Rossby waves affecting large parts of Java, including Jakarta, contributing to the heavy rainfall.
• 😀 Sea surface temperatures in the northern waters of Jakarta remain warm, which also supports the formation of significant rain clouds.
• 😀 The BMKG predicts that heavy rainfall will continue in the Jabodetabek area for several more days, accompanied by lightning and strong winds, although the intensity is expected to decrease over time.

Q & A

What caused the flooding in Jakarta?

The flooding in Jakarta was caused by heavy rainfall that started on Saturday morning, which led to water levels rising up to 30 cm in certain areas. Additionally, blocked drainage systems and tidal water levels exacerbated the flooding.

Which areas in Jakarta were most affected by the flooding?

The most affected areas by the flooding were Duren Sawit in East Jakarta and Kapuk Muara in North Jakarta.

What was the water level in Duren Sawit, East Jakarta?

In Duren Sawit, East Jakarta, the water level reached approximately 30 cm.

How did the heavy rainfall affect the roads?

The heavy rainfall caused the streets, such as Radin Inten in Duren Sawit, to become flooded. This made the roads passable only in certain parts, and some vehicles had to be pushed due to engine failure caused by water infiltration.

What efforts were made to address the flooding in Duren Sawit?

Local authorities, including the water resource officers from Duren Sawit, worked to clear clogged drainage channels in an attempt to help the water recede.

Was the situation in Kapuk Muara, North Jakarta, different from Duren Sawit?

Yes, while the water levels in Kapuk Muara had begun to recede by Saturday night, the flooding still affected daily life, with water levels reaching 30 cm. People had to carry out their activities in the flooded streets.

What additional environmental factors contributed to the flooding?

In addition to heavy rainfall, tidal surges worsened the situation in areas like Kapuk Muara, where rising sea levels contributed to the flooding.

What did the Meteorology, Climatology, and Geophysics Agency (BMKG) say about the cause of the heavy rainfall?

BMKG explained that the intense rainfall was caused by a regional-scale atmospheric phenomenon, including the Madden-Julian Oscillation (MJO), which influences weather patterns, particularly during the dry season, resulting in heavier-than-usual rain.

How did the MJO affect the weather in Jakarta?

The Madden-Julian Oscillation (MJO) contributed to the increased likelihood of heavy rainfall, particularly during the dry season, by enhancing cloud growth and rainfall in areas like Jakarta.

What can be expected in the coming days regarding rainfall in Jakarta?

BMKG predicted that heavy rainfall would continue in Jakarta and surrounding areas (Jabodetabek) for the next few days, with potential thunderstorms and strong winds. However, the rainfall intensity is expected to decrease over time.
