Animations of 25 Aug 2012 from the 200-m model

• 200-m model
• 3-h period
• Liquid, ice and rain converted approximately to an extinction coefficient
• Shadowing implemented by computing a unit vector pointing along the spatial gradient of the extinction, then shading according to the angle between this vector and the direction to the sun
• Rain rate shown below on a log scale between 0.01 and 10 mm/h

Animation 1: Ice and rain only

• Vertical scale stretched by factor 3.33
• Liquid removed completely
• 280x200 km region

Animation 2: Zoom into an storm over the Severn estuary

• Aspect ratio 1:1
• 50x50 km region
• Plotted region follows storms
• Liquid extinction coefficient reduced by a factor of 10

Animation 3: Zoom into an storm over Wiltshire

• Aspect ratio 1:1
• 50x50 km region
• Plotted region follows storms
• Liquid extinction coefficient reduced by a factor of 10
