Brutal heatwaves that persist through the night follow a hidden pattern

Scientists have discovered that brutal heatwaves that won't cool down even at night follow a hidden rhythm of 10 to 30 days, which could help forecasters warn of dangerous heat much earlier. This pattern recognition could give winemakers valuable advance warning to protect their vineyards from heat stress during critical growing periods. Understanding these rhythms means the industry might better prepare for extreme temperatures before they strike.
