Animations of 25 Aug 2012 from the 1.5-km model

• 1.5-km model
• 340 x 340 x 15 km domain centred on Chilbolton
• 3-h period
• Vertical scale stretched by factor 3.33
• 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: All cloud

Animation 2: Ice and rain only

• Liquid removed completely

Animation 3: Zoom into an 84x84 km region

• Aspect ratio 1:1
• Plotted region follows storms
• Liquid removed and ice extinction halved

Animation 4: Zoom into a 54x54 km region

• Aspect ratio 1:1
