• Examples: – Range check – Buddy check (comparison to nearby stations) – Comparison to first guess fields from previous model run – Hydrostatic and vertical consistency checks for soundings. • A very important issue for the forecaster--sometimes good data is rejected and vice versa. Bad Observation Objective Analysis/Data Assimilation • Often starts with a "first guess", usually the gridded forecast from an earlier run (frequently a run starting 6 hr earlier). Often called the "Nowcast" model • This first guess is then modified by the observations. • Adjustments are made to insure proper balance. • Objective Analysis/Data Assimilation produces what is known as the model initialization, the starting point of the numerical simulation. Crunching weather data FORECASTING There are 3 basic methods of forecasting: • Persistence • Experience • Computer Modeling PERSISTENCE: •Not much is going to change. •Tomorrow will be like today. •Works great in summer. •Not so good the rest of the year. EXPERIENCE: •Forecast what was seen before to repeat.
