VIVA – As Indonesian people are experiencing heatwave lately, the Meteorology and Climatology Agency (BMKG) announced on Friday that extreme ultraviolet (UV) rays have hit several regions in Indonesia, including the capital city of Jakarta.
From the agency data, it is stated that the very high and extreme UV index occurs when the intensity of solar radiation is highest during the day, between 12 pm to 3 pm local time. And will move down to the low category in the afternoon. This pattern depends on the geographical location and elevation of a place, the position of the sun, the type of surface, and the cloud cover.
"For locations with general weather conditions predicted to be sunny-cloudy in the morning until noon can potentially cause the UV index in the very high and extreme categories during the day," the BMKG wrote as quoted from the official website on Friday.
