WMO: 2017 records

2017 expected to be third hottest on record 

The World Meteorological Organization (WMO) has released its provisional Statement on the State of the Climate. It estimates that 2017 is likely to be one of the warmest years for global average surface temperature, with many high-impact events including catastrophic hurricanes, floods, heatwaves and droughts.  The Statement was released on the opening day of the United Nations climate change conference in Bonn.

Nacreous clouds

Clouds that have a vivid iridescent appearance. They are formed of small droplets which scatter light in such a way that creates the distinctive luminescent appearance. Nacreous clouds form below -78 °C temperatures at altitudes 68,500 - 100,000 ft above the Earth's surface (in the lower stratosphere) over polar regions.They are also known as Polar Stratospheric Clouds (PSC) or 'mother-of-pearl clouds'. 

Morning glory

Rare, elongated cloud bands (visually similar to a roll cloud, or arcus cloud) that usually appear in the morning hours, when the atmosphere is relatively stable. Morning glory clouds result from perturbations related to gravitational waves in a stable boundary layer. They are similar to surfave water ripples with several parallel morning glories often seen spreading in the same direction.

Monsoon

A seasonal shift in wind direction that brings alternate very wet and very dry seasons to India and much of South-East Asia. It is a thermally-driven wind arising from differential heating between a land mass and the adjacent ocean that reverses its direction seasonally.

Typhoon Lan

Typhoon Lan (known as Typhoon Paolo in the Philippines) killed at least two people in Japan, with more than 200,000 households advised to evacuate on 22nd – 23rd October. The Typhoon was classified as a strong category 4 storm at its peak but making landfall as a category 2, it brought heavy rainfall, sustained winds of 100 mph, high waves and flooding to parts of Japan.
