It is understood that although Brazil is in the southern hemisphere and in the tropics, under normal circumstances, Brazil will have four seasons a year, and every year from June to September will usher in winter.

However, this year, due to the influence of El Ni ñ o, winter shows signs of coming early. As a result, Brazil's National Meteorological Institute announced on April 18 that the first cold wave in 2024 will be felt first in the south, and then to the southeast and central regions.

And there will be cooling in cities such as Curitiba, Rio de Janeiro and S ã o Paulo Victoria, which could be more than 10 ℃ and temperatures around 10 ℃ to 17 ℃.

In addition, frosts are expected in the southern regions of Grand Southern, Santa Catarina and southern Parana. According to the meteorological department, a cold peak, such as a drop in temperature in the future, has been linked to an outer cyclone, which has caused a lot of rain in the south.

However, according to Epagri/Ciram, which monitors the weather in Santa Catarina, the lowest temperature recorded in the morning was 1.95 ℃ in Bom Jardim da Serra, in the mountains of Santa Catarina, while the morning temperature in Urupema in that state was only 2.52 ℃, according to the Civil Defense Department. According to the department's data, the mountains of Santa Catarina and high-altitude areas of the west and some areas of Parana are as low as 5 ℃, which is enough to cause frost, so notices are issued to alert local residents and farmers to the effects of frost on crops.

In addition to recent concerns about weather changes, there are also concerns about the future. According to the latest weather forecast from the latest Climate Forecast Center of the Meteorological Bureau, La Nina weather will form between June and August, and La Nina weather will last for the whole second half of the year.

Brazil predicts that the return of La Nina phenomenon may reduce rainfall and cold weather in southeastern Brazil and increase rainfall and humidity in the northeast. The cold weather will cause a sharp drop in temperature in coffee and other crop-producing areas, which will bring frost disasters and damage the output of coffee and other agricultural products in the current and future seasons.

According to botanical experts, when the temperature drops sharply during frost, the water in plant cells will crystallize and form sharp crystals, which pierce the intima and cell wall and destroy plant cells. It will also cause damage to some dormant plants, damaging cell walls and tissue structures, causing them to fail to grow and bloom normally. Frost will also cause a certain degree of damage to the fruit of crops, resulting in the decline of fruit quality, deformation, peel rupture and so on, and finally affect the yield of crops.

In addition, as early as 2021, Brazil suffered its worst frost in decades, wreaking havoc on crops such as coffee, sugar cane and corn, and pushing up the prices of a range of crops, including sugar, corn and coffee. Therefore, recently, the weather department has issued a warning to remind farmers to take preventive measures.
