Making Progress on Drought Management: Improvements in Seasonal Precipitation Forecasting
June 9th event held in Irvine
Over the past decade, climate whiplash in California has been evident in the big swings from very dry years to very wet years and back again. That dynamic was seen in microcosm within the 2021-2022 water year as we went from a relatively wet beginning from Oct.-Dec. to the driest Jan.-March period in the state’s history, rendering the spring’s precipitation “too little, too late.”
How has this new reality affected our reliance on historical patterns to forecast California’s water supply? What efforts are being made to improve precipitation forecasting at varying time scales through new science, models and technology? Participants found out at our one-day event June 9 in Irvine, Making Progress on Drought Management: Improvements in Seasonal Precipitation Forecasting.
Participants heard about the latest advancements in sub-seasonal to seasonal forecasting — weather predictions from two weeks to a season ahead — and how these predictions could improve management of water infrastructure including dams, flood storage and reservoirs. Preliminary research for the Upper Colorado River Basin was also covered.
The event was ideal for anyone involved in managing water resources. It covered what is and isn’t known about forecasting California’s winter precipitation weeks to months ahead, the skill of present forecasts and ongoing research to develop predictive ability. Other topics included experimental forecasts of atmospheric rivers and winter blocking conditions.
