The “Storm Helicity” product provides forecasts every three hours for the next seven days, measuring helicity in square meters per square second (m²/s²). Helicity is a crucial meteorological parameter that quantifies the amount of atmospheric rotation and its vertical distribution.
- High helicity values: Indicate an increased potential for severe storm formation, including tornadoes and supercell storms.
- Low helicity values: Suggest less atmospheric rotation, reducing the likelihood of extreme weather events.
Helicity enhances air circulation and convection, creating a favorable environment for extreme meteorological phenomena. Monitoring this index is essential for predicting severe storms and improving weather forecasting accuracy.
