<p>The convective indicator orange warning estimates the expected number of thunderstorm occurrences in a year with intensity corresponding to an orange warning. The intensity classes correspond to the three commonly used warning colours in operational weather forecasting: yellow = remarkable weather, orange = severe weather, red = extreme weather. The indicator is calculated on a central European domain and includes all sub-processes related to thunderstorms (i.e., large hail, excessive rain, severe wind gusts and tornadoes).</p>
<p>The indicator is calculated by applying an additive logistic regression which blends the occurrence/non-occurrence of thunderstorms with a set of predictors representing key ingredients for thunderstorms (i.e., instability, moisture, lift, vertical wind shear). Thunderstorm occurrences used to develop the statistical model are derived by merging information from fire brigade reports, eyewitnesses and meteorological measurements and categorized based on elaborated criteria catalogues. Unit: 1.</p>
