1.4. Numerical Weather Prediction (NWP) Models:
Sophisticated computer models, like the Global Forecast System (GFS) and the High-Resolution Rapid Refresh (HRRR), are fed the collected data. These models solve complex equations that simulate atmospheric processes, predicting future weather conditions based on current observations and projected atmospheric dynamics.
2. Data Assimilation: Weaving Together the Information
Raw data from various sources isn’t immediately useful for forecasting. The next step is data assimilation – a process that combines observations with NWP model predictions to create a more accurate and consistent picture of the current atmospheric state. Advanced algorithms are used to optimally blend the diverse data sets, minimizing errors and improving forecast accuracy.
3. Model Interpretation and Ensemble Forecasting: Understanding the Possibilities
NOAA forecasters don’t simply rely on a single model output. Instead, they use ensemble forecasting, running multiple weather models with slightly different initial conditions. This allows them to assess the range of possible outcomes and identify areas of uncertainty. By examining the spread of model forecasts, they can better understand the strengths and weaknesses of individual models and quantify forecast uncertainty.
4. Human Expertise: The Critical Role of the Forecaster
While technology plays a significant role, human expertise is essential in weather forecasting. Experienced NOAA forecasters in Spokane possess a deep understanding of local geography, climatology, and weather patterns. They utilize their knowledge and judgment to interpret model outputs, considering factors that models might miss. This includes analyzing local terrain effects on wind and precipitation, understanding the influence of the Cascade Mountains on Spokane’s weather, and recognizing subtle patterns that might indicate developing weather events. They also incorporate local observations and knowledge from citizen reports.
5. Forecast Dissemination: Getting the Information to the Public
Once the forecast is crafted, it needs to reach the public effectively. NOAA uses various channels to distribute weather information, including:
5.1. Public Forecasts:
NOAA’s website and mobile app provide detailed forecasts for Spokane and surrounding areas, including hourly and daily predictions, and weather alerts.
5.2. Media Partnerships:
NOAA collaborates with local news stations and media outlets to share forecasts with a broader audience.
5.3. Specialized Forecasts:
NOAA also provides specialized forecasts for agriculture, aviation, and other sectors that have specific needs for weather information. For example, forecasts for wildfire risk in eastern Washington are crucial during dry seasons.
Understanding the Limitations of Weather Forecasting
It’s crucial to understand that weather forecasting is not an exact science. While accuracy has improved significantly, there are inherent limitations due to the chaotic nature of the atmosphere and the complexity of atmospheric processes. Even the best forecasts have uncertainties, and unexpected events can occur. The skill of a forecaster lies in effectively communicating both the certainties and uncertainties associated with a forecast.
