<p>
De Lift-index  (ook wel 'stijgingsindex') is de temperatuur op het 500 hectopascal - vlak 
(gemiddeld is dat op ongeveer 5500 meter hoogte, of 18.000 voet boven zeeniveau), minus de temperatuur 
van een opstijgend luchtdeeltje vanaf de grond op dit luchtdrukniveau. 
Als de Lift-Index (sterk) negatief is dan geeft het aan dat een luchtdeeltje (veel) warmer is dan zijn 
omgeving, en het luchtdeeltje zal blijven stijgen. Omdat onweerswolken gevoed worden door sterk stijgende 
luchtstromen is de Lift-Index een goede indicatie voor de kans op de ontwikkeling van (zware) onweersbuien.

  <div class="eI2"><a href="http://www.knmi.nl/" target="_blank">HARMONIE-AROME</a> The non-hydrostatic convection-permitting HARMONIE-AROME model is developed in a code cooperation of the HIRLAM Consortium with Météo-France and ALADIN, and builds upon model components that have largely initially been developed in these two communities. The forecast model and analysis of HARMONIE-AROME are originally based on the AROME-France model from Météo-France (Seity et al, 2011, Brousseau et al, 2011) , but differ from the AROME-France configuration in various respects. A detailed description of the HARMONIE-AROME forecast model setup and its similarities and differences with respect to AROME-France can be found in (Bengtsson et al. 2017). [From: HIRLAM (2017)]<br>

  <div class="eI2">Numerical weather prediction uses current weather conditions as input into mathematical models of the atmosphere to predict the weather. Although the first efforts to accomplish this were done in the 1920s, it wasn't until the advent of the computer and computer simulation that it was feasible to do in real-time. Manipulating the huge datasets and performing the complex calculations necessary to do this on a resolution fine enough to make the results useful requires the use of some of the most powerful supercomputers in the world. A number of forecast models, both global and regional in scale, are run to help create forecasts for nations worldwide. Use of model ensemble forecasts helps to define the forecast uncertainty and extend weather forecasting farther into the future than would otherwise be possible.<br>
