Mesoscale Weather Prediction<br />

◮ Strong and disastrous impact <strong>of</strong> many weather extremes calls<br />

for reliable forecasts<br />

◮ ”Although forecasters have traditionally viewed weather<br />

prediction as deterministic, a cultural change towards<br />

probabilistic forecasting is in progress.” (T N Palmer, 2002)<br />

◮ Weather extremes do not come ”Out <strong>of</strong> the Blue”<br />

◮ Numerical weather forecast models provide reliable forecasts<br />

<strong>of</strong> the atmospheric circulation prone to generate extremes<br />

◮ Combination <strong>of</strong> dynamical and statistical analysis methods<br />
