More rain ahead in Jakarta: Experts<\/p>\n
Abdul Khalik, The Jakarta Post, Jakarta<\/p>\n
Jakarta and its surrounding areas as well as West Java will see
\nmore rain in the days ahead, experts say.<\/p>\n
Researcher at the National Space and Aviation Agency (Lapan)
\nErna Sri Adiningsih said on Sunday that day's satellite data
\nsuggested clouds from the Indian Ocean in the South and around
\nthe Philippine area in the North were moving across to Sumatra,
\nKalimantan and the western part of Java.<\/p>\n
She said a monsoon in areas between the Philippines and
\nSulawesi was likely to cause denser cloud coverage to the south
\nin the next few days.<\/p>\n
"The sun is in the northern hemisphere now. This has created
\nlower pressure areas around the Pacific Ocean and the Philippines
\nand higher temperatures. Extreme pressure differences caused a
\nmonsoon in the area, which in turn caused heavy cloud coverage,
\nrain and lightning in several areas, including West Java and
\nJakarta," Erna said.<\/p>\n
The rain could also be blamed on the unusually high
\ntemperature of the sea's surface in the south, which produced
\ndenser cloud coverage and in turn created rain, she said.<\/p>\n
"We call the anomaly a negative Dipole Mode Event, caused by a
\nmonsoon and the intense rays of the sun. The Indian Ocean is
\nwarmer than usual. This will last for months, possibly as late as
\nSeptember or October," Erna said.<\/p>\n
Erna said two phenomena had caused rainfall to be 15 percent
\nheavier than normal:<\/p>\n
The Meteorology and Geophysics Agency (BMG) previously said
\nthe dry season would start in Jakarta in April and end in
\nNovember. In June and July, however, sudden copious rainfall has
\nbeen regular, causing floods in the capital.<\/p>\n
Heavy and continuous rain last Friday evening flooded the
\ncity's thoroughfares, causing traffic jams until late at night.<\/p>\n
Last week, the BMG said this year's dry season was much like
\nthe usual wet season as cloudbursts had been common.<\/p>\n
The BMG's head of meteorological information Achmad Zakir said
\nrain would fall at least until the end of July as besides the
\ncyclone in the north, the temperature of the sea's surface was
\nsimilar to that of the rainy season.<\/p>\n
He said rain would fall in southern, central, and eastern
\nparts of Jakarta in the afternoon, while rain would fall in
\nBekasi and Bogor in the evening.<\/p>\n
Achmad predicted medium to heavy rainfall with lightning in
\nthe evening and light rain in the morning.<\/p>\n
He said the western part of Java, particularly Bandung, Merak,
\nSerang, and Cilacap, as well as several parts of Sumatra, would
\ncontinue to have rain until the end of July.<\/p>",
