Recently, a lot of foam has appeared on Australian beaches. Where do these foams come from?

Overseas Network, December 15th. Heavy rains have hit Australia recently, causing flash floods and extremely large tides. A large amount of foam rolled up on the beach. Some local residents played new tricks and spontaneously organized activities such as boating and swimming, and even Some residents ran around naked. According to the British "Daily Mail" report on the 15th, severe weather has caused road closures in many places in Australia, isolated small communities, and affected approximately 1,000 houses. The State Emergency Service (SES) has issued a flood evacuation warning and more than 300 emergency personnel have been dispatched to northern New South Wales to support operations alongside local rescue workers.

During the continuous heavy rain, many beaches were covered with thick foam. Five people were seen swimming at a Gold Coast beach. One of the men was "buried" by rolling sea foam and resurfaced seconds later. On the 14th, a woman was filmed risking her life by diving into the water and grabbing two washed away metal barrels of beer in the knee-deep foam. Three men were filmed running naked in the rain in Byron Bay. According to reports, foam can form when storms hit and the ocean is stirred by wind and waves. Currently, Queensland and New South Wales are experiencing massive bubbles following a "once-in-100-year storm". New South Wales Prime Minister Gladys Berejiklian said in an interview: Meteorological experts have warned that the La Nina phenomenon will have an impact across Australia. We need to expect the unexpected. The situation may be the worst in years. ?

According to the Global Network, brown foam waves appeared on the coast of Australia, which can completely submerge people. On December 14, a strong storm occurred on the east coast of Australia. The extreme weather caused foam waves to appear on some beaches. In the video, waves of foam are washed up on the beach, and many people jump in to play. The foam is enough to drown a person. It is reported that these brown foams are formed when heavy rains bring organic matter from land to the ocean and are then impacted by waves.
