In countries like Japan and South Korea, the summer has a rainy season. For a long time, people could expect this rain to arrive each year.
However, this year the rainy period was much shorter than usual. This change has made things difficult, especially for farmers who need the water for their crops.
Scientists are studying why this is happening. They believe that climate change is the main reason. It has made the summer rains more unreliable.
Being unreliable means that people can no longer count on the rain to come at the same time each year. This uncertainty affects farming, water supplies, and everyday plans.
