“World Meteorological Day takes place every year on 23 March and commemorates the coming into force on 23 March 1950 of the Convention establishing the World Meteorological Organization. It showcases the essential contribution of National Meteorological and Hydrological Services to the safety and wellbeing of society and is celebrated with activities around the world. The themes chosen for World Meteorological Day reflect topical weather, climate or water-related issues” (https://public.wmo.int/en/resources/world-meteorological-day).
In celebration of world meteorological day, we are showcasing Christina Gabriele Liesker’s MSc research project:
Characteristics of warm season supercell thunderstorms over the Gauteng and Mpumalanga Provinces of South Africa
The figure shows the track distribution of all left-moving supercells identified within the warm seasons of 2010 to 2020. This figure was created using a Kernel Density Estimation analysis and was done using the left-moving supercell’s vector path (based on the centroid position of the thunderstorm). A 1 km by 1 km grid was created over the data and was used to count the number of lines (shown by the colours) that occurred within a 10 km search radius of each grid cell.
A number of hotspots in active supercell regions were identified. This included the south-western and eastern Highveld of Gauteng and south-eastern parts of Mpumalanga (warm shades).
