If you were in the Newton area on 25 May, you may have spotted this huge woolly blanket in the sky!

This blanket of dense clouds was formed as the top of a cumulonimbus cloud collapsed following strong thunderstorms across Singapore earlier that morning.

Named “cirrus spissatus”, these rarer upper atmosphere clouds are thicker and denser, and would block out the sun. The Latin word “spissatus” in its name describes its thicker appearance.

For those who answered A, B or C, you may be experiencing pareidolia! It is the term used for the human tendency to see a specific image in random visual patterns. Most of us have experienced it at least once! #WeatherWednesday

Did you manage to catch these pastel-coloured altocumulus clouds at sunset?

When the sun is at a low angle on the horizon, sunlight travels across a longer distance through the atmosphere before reaching our eyes. As a result, blue colours are scattered by atmospheric particles, leaving behind brilliant hues of pink, orange and yellow.

Altocumulus clouds putting on a post-storm sunset show! 🌅☁️

After a thunderstorm mid-level clouds like altocumulus are often spotted. These clouds are the ideal backdrop for vibrant skies because they catch sunlight, creating those deep, fiery colours we love.😍 #WeatherWednesday

Ever wondered how we measure rainfall in Singapore? 🌧️ It is measured with tipping bucket rain gauges, which use a seesaw mechanism. The bucket fills, tips and repeats. More tips = higher rainfall, faster tips = higher intensity.

Stevenson screens play a crucial role in measuring the true air temperature. Thermometers are housed in a Stevenson screen, sheltering them from direct solar radiation while allowing air to circulate. To avoid heat from the ground from affecting the temperature measurement, the screens are placed 1.25m to 2m above ground. Learn more: go.gov.sg/weather-instruments
