JAKARTA - People in Jakarta are amazed by the view of the blue sky that adorns the city all day long. In fact, the sky is so blue in Jakarta that it has become a trending topic on Twitter.

Not a few netizens have uploaded photos of Jakarta's sky weather which is so different from usual. The sky looks so bright blue with a little white cloud cover around it that spoils the eyes.

Information about the bright sky in Jakarta has also been confirmed by the Meteorology, Climatology and Geophysics Agency (BMKG). According to the Head of Dissemination of Climate and Air Quality Information at BMKG, Hary Djatmiko, Jakarta's sky conditions today occur due to the transition from dry to rainy season.

"The phenomenon of sunny weather with the appearance of a blue sky is a natural phenomenon that can occur in all seasons. This is indicated by the wind that blows quite fast and the humidity is quite dry compared to the previous few days," Hary told VOI, Tuesday, December 1.

He explained the current weather conditions in the Jakarta area, with an average temperature of 23 to 31 degrees Celsius and humidity of 75 to 95 percent. This condition hinders the formation and growth of rain clouds.

In addition, Hary said that at this time the position of the sun's pseudo movement was south of the Equator up to 23.5LS. This means that the sunlight emitted and received by the earth, especially the Indonesian region which is south of the equator, is very optimal.

"This condition brings various types of long waves, one of which is visible light (mejikuhibiniu color) which enters the Earth and is driven and filtered by particles in the atmosphere dominated by blue, indigo and purple colors. That is what causes the Jakarta sky to appear and visible to our eyes is blue, "he explained.

A similar sentiment was also conveyed by the Head of the National Aeronautics and Space Agency (Lapan) Thomas Djamaluddin, who said that the phenomenon of the blue sky in Jakarta today is an ordinary weather dynamic. Where the sky is clear this will not happen for a long time.

"It's sunny because it happens that there are no clouds. But it could be that in the next area there are clouds. It is still the end of the transition period, the transition from dry to rainy season. The formation of clouds is not too much, so sometimes it is sunny," said Thomas.
