**How Climate Cycles Align: When Do 14-Year and 21-Year Patterns Coincide?**
With climate change shaping weather patterns across the United States, scientists increasingly track long-term cycles that influence temperature, rainfall, and extreme events. Among these, a noted pattern involves two recurring natural cycles: one spanning 14 years and the other 21 years. When will these patterns converge again? Understanding when they align offers valuable insight into long-term climate trends and seasonal forecasting. --- ### Why Climate Cycles Like 14-Year and 21-Year Periods Are Gaining Attention Climate cycles influence regional weather in measurable ways—from shifts in jet stream behavior to fluctuations in rainfall and storm frequency. While many focus on immediate weather, long-term
