"ลานีญา" หายไปแล้ว โลกเข้าสู่สภาวะความเป็นกลาง เปิดผลกระทบไทยอากาศป่วน | TNN ข่าวเที่ยง | 18-4-68

Summary

The global climate is currently in a neutral state after transitioning from the La Niña phenomenon. La Niña, which causes cooler ocean temperatures and increased rainfall in regions like Southeast Asia, has dissipated, leaving behind a balanced climate. This change impacts various regions differently: Southeast Asia faces heavy rainfall and flooding risks, while parts of South America and the U.S. are dealing with droughts. Thailand is experiencing more rainfall than usual, with potential flooding. The ongoing global warming crisis continues to exacerbate extreme weather patterns, making preparation for natural disasters essential.

Takeaways

• 😀 La Niña has recently ended, transitioning into a neutral phase in early 2025, marking a shift from the extreme weather conditions it caused previously.
• 🌧️ La Niña brings heavy rainfall to Southeast Asia and Australia, increasing the risk of flooding and landslides in these regions.
• 🔥 On the contrary, La Niña triggers droughts and wildfires in South America and the United States, leading to dry conditions and cracking soil.
• 🌐 The current neutral phase signifies that conditions are not extreme enough for either El Niño or La Niña, but some weak La Niña-like effects may still persist.
• 🌡️ Global warming is exacerbating the situation, with oceans absorbing over 90% of the heat, causing record-high temperatures in 2023 and 2024.
• 💨 The United States experienced a series of 18 storms and 11 hurricanes in 2024 due to shifting climate patterns, which remain unpredictable.
• 🇹🇭 Thailand is experiencing increased rainfall compared to last year, with the rainy season starting earlier than usual in 2025, raising concerns about flooding.
• 🌦️ From June to August, rainfall in Thailand will be close to normal, but there could still be dry spells during the period.
• 💧 By September, heavy rain is expected in northern and northeastern Thailand, with potential for significant flooding.
• 🌞 Overall, while Thailand's summer in 2025 won't be as extreme as last year, temperatures could still reach around 40°C, and the drought situation is expected to be mild.

Q & A

What is the main global event discussed in the script?

The main event discussed is the transition from the La Niña phenomenon to a neutral climate state, which occurred in early 2025 after a period of La Niña conditions that began in 2022.

What is La Niña and how does it impact global weather?

La Niña is a climate phenomenon characterized by cooler-than-normal sea surface temperatures in the central and eastern Pacific Ocean. It typically leads to increased rainfall in Southeast Asia and parts of Australia, while causing droughts and fires in South America and parts of North America.

How does the neutral state differ from La Niña and El Niño?

A neutral state refers to a situation where ocean temperatures and atmospheric conditions are not extreme enough to cause El Niño (which brings warmer temperatures and drier conditions) or La Niña. It results in more balanced weather conditions globally.

What is the expected impact of the neutral state on Thailand's weather?

In Thailand, the neutral state is expected to bring above-average rainfall in April and May, a return to near-normal rainfall levels from June to August, and heavy rains in September, especially in the northern and northeastern regions. There is also a likelihood of early rains and milder dry conditions.

What specific weather events are expected in Thailand during the transition to a neutral state?

In Thailand, the expected weather events include early onset of the rainy season, potential flooding, and a moderate summer with temperatures reaching around 40°C, though not as extreme as the previous year.

How does the global warming trend relate to the weather phenomena discussed?

Global warming exacerbates weather phenomena like La Niña and El Niño by increasing the amount of heat trapped in the Earth's oceans. This results in record-breaking global temperatures, as seen in recent years, and contributes to the unpredictability of weather patterns.

What role do oceans play in the Earth’s temperature regulation?

Oceans absorb over 90% of the heat generated by global warming. This leads to rising sea temperatures, which, in turn, influence weather patterns, including the intensity of El Niño and La Niña events.

What can be expected in terms of weather extremes in the coming years?

While the transition to a neutral state may reduce the intensity of extreme weather events, the ongoing impact of global warming could still result in increased storm activity, rising temperatures, and more extreme weather events globally, including in regions like the United States and Southeast Asia.

How long is the neutral state expected to last?

The neutral state is expected to persist throughout 2025, with its peak occurring between August and October, after which it may either stabilize or transition into another climatic phase.

Why is it important for Thailand to prepare for changes in the weather?

Thailand must prepare for potential flooding, increased rainfall, and early onset of the rainy season, which could disrupt daily life and cause damage to infrastructure. Being prepared for these shifts will help mitigate the risks associated with extreme weather events.
