Making a fog-cast. World Meteorological Day
'When clouds appear like rocks and towers, the Earth's refreshed with frequent showers.' There's a whisper of truth to this old proverb for the storm clouds, also known as cumulonimbus or anvil clouds, which are pictured here. Today, on World Meteorological Day, we honor the marvel that is our atmosphere. This observance, first held in 1961, commemorates the establishment of the World Meteorological Organization and recognizes the vital role meteorology plays in our lives. Weather forecasts may not always appear reliable, but thanks to advances in technology like satellites and supercomputers, they have come a long way. Global weather models provide forecasts for up to 16 days and, the average lead time for tornado warnings is now around 15 minutes. Cheers for the progress made and much more to come!
