TRIBUNBATAM.id, BINTAN - The Meteorology, Climatology and Geophysics Department (BMKG) Raja Haji Fisabilillah (RHF) Tanjungpinang has released weather forecasts for Tanjungpinang City and Bintan Regency, Riau Islands (Kepri) for the next three days. 

Dynamics analysis, the sea surface temperature (Sea Surface Temperature or SST) as of October 15, 2021 around the waters of the Riau Islands, especially in the waters of Bintan Island, is generally still in warm conditions ranging from 29 - 31°C and the SST anomaly in the waters of the Riau Islands tends to positive value between 1.0 sd 2.0°C. 

The updated ENSO index is still worth 0.61 and is in a weak La Nina condition, so in general it doesn't have a significant impact on increasing convection activity in the Indonesian region. It is estimated that the Weak-Neutral La Nina condition will last until February-April 2022. 

Based on the analysis of atmospheric dynamics, it shows that the influence of global scale weather phenomena (ENSO), MJO and IOD has no effect on increasing convection activity in the Bintan Island region and its surroundings. 

The SST value which is still warm with a positive SST anomaly value indicates significant evaporation activity, so that it can increase the supply of water vapor to the atmosphere and support the growth of convective clouds in the Bintan Island region. 

Local scale weather phenomena in the form of wind bends (shearline) and wind convergence (convergence) are still dominant around Bintan Island. 

Atmospheric conditions in the lower to middle layers, which are predicted to remain quite wet for the next few weeks, can also support the formation of convective rain-producing clouds. 

This indicates that the atmosphere is still wet and has the potential for the growth of convective clouds in the Bintan Island area and its surroundings.  

For information, the following are the weather forecast report in Tanjungpinang City and Bintan Regency for the next three days. 

October 17, 2021, Tanjungpinang City, cloudy with the potential for light-moderate rain in the afternoon-evening. Bintan Regency, cloudy and potentially light-moderate rain in the afternoon-evening. 

October 18, 2021, Tanjungpinang City, cloudy and with the potential for light-moderate rain in the morning-afternoon. Bintan Regency, cloudy and potentially light-moderate rain in the morning-afternoon. 

October 19, 2021, Tanjungpinang City, Cloudy with the potential for light-moderate rain during the day. Bintan Regency, cloudy and potentially light-moderate rain during the day.
