Indonesia Seeds Clouds to Block Rain from Flooded Capital
Indonesia's air force has seeded clouds with salt in an effort to stop rain from falling on the flooded capital, Jakarta.
The seeding operation follows deadly flash floods and landslides that hit the capital after some of the heaviest rain ever recorded.
Indonesian officials said that as of Friday, at least 43 people had been killed in the disaster. Tens of thousands of people have been displaced.
Cloud seeding is a process that involves shooting salt into clouds in an attempt to create artificial rain. It is often used in Indonesia to help put out forest fires. The current operation aims to get the clouds to drop water and break up before they reach Jakarta.
Indonesia's air force teamed up with the country's technology agency to carry out three rounds of cloud seeding on Friday. Officials said more cloud seeding would take place as needed.
The latest flooding followed heavy rainfall on December 31 and into the early hours of New Year's Day. The water covered large areas of Jakarta and nearby towns. The area is home to about 30 million people.
The start of 2020 weather was "one of the most extreme rainfall" events since record keeping began in 1866, Indonesia's weather agency said Friday. The officials said climate change had increased the risk of extreme weather. They warned that heavy rainfall could reach a high point in mid-January and should be expected to last until mid-February.
News videos showed floodwaters spreading across Jakarta. Images showed groups of people walking through water and mud-covered cars, some of them sitting on top of each other.
President Joko Widodo blamed delays in flood control projects for the disaster. Among the projects is the building of a canal that has been delayed since 2017 because of property right issues.
In 2007, more than 50 people died in one of the capital's deadliest flood disasters. In 2015, floodwaters covered much of the city center after canals overflowed.
Jakarta has been slowly sinking. A main cause is the amount of ground water being drawn out from under the city. Rising sea levels have made the threat of flooding even worse.
Last year, Widodo announced he would move Indonesia's capital to East Kalimantan province on Borneo island to reduce the burden on overpopulated Jakarta.

人工增雨是一种向云中撒盐以产生人工降雨的过程 。在印尼，这种方式常用来帮助扑灭森林大火 。目前采取这一行动的目的是让云层滴水，让其在抵达雅加达之前就分解掉 。
周五，印尼空军与该国技术机构合作进行了三轮人工降雨 。官员们表示，将根据需要进行进一步的人工增雨 。
最近的一次洪水发生在12月31日的强降雨之后，并一直持续到元旦凌晨 。洪水淹没了雅加达的大片地区和附近的城镇 。该地区约生活着3000万人口 。
印尼气象局周五表示，新年伊始的天气是自1866年开始记录以来“最极端的降雨之一” 。官员们表示，气候变化增加了极端天气的风险 。他们警告说，强降雨可能在1月中旬达到最高峰，预计将持续到2月中旬 。

印尼总统佐科·维多多(Joko Widodo)将洪灾归咎于防洪项目的延误 。其中一个项目是修建一条运河，由于产权问题，该项目自2017年以来一直被搁置 。
2007年，雅加达最致命的洪灾之一导致50多人遇难 。2015年，运河泛滥后，洪水淹没了市中心的大部分地区 。
雅加达一直在缓慢下沉 。其中一个主因是城市下面大量的地下水从被抽出 。海平面上升使洪水的威胁与日俱增 。
