Preciptiation—rain and snow (largely)—is mostly a function of the vapor content in the air.
365 Days of Climate Awareness 122 – Extreme Weather Events: Extreme Heat
“The frequency and intensity of hot extremes have increased and those of cold extremes have decreased on the global scale since 1950.”

365 Days of Climate Awareness 121 – Extreme Weather Events: Droughts
Extreme events are one of the thorniest areas of climate change research: long-term trends, on a global or even regional scale, to singular events (even multi-year events such as droughts can be).

365 Days of Climate Awareness 120 – Global Weirding
“Global weirding” is the term coined by environmentalist Hunter Lovins for the concept of extreme weather events connected with global warming.

365 Days of Climate Awareness 119 – The Great Pacific Garbage Patch
There is a misconception with the term “garbage patch”, matching the sensationalistic photos, of this massive sprawl of floating trash, like an oceanic landfill, extending hundreds of miles.

A gyre is a rotating surface current.

365 Days of Climate Awareness 117 – Upwelling
Upwelling, where winds pull deeper ocean water to the surface, is entirely a function of Coriolis-related Ekman transport, where surface water moves away at a 90° from the wind.

365 Days of Climate Awareness 116 – Ekman Transport
There’s an odd phenomenon in geophysical fluid dynamics called “Ekman transport”, named for fluid dynamicist Vagn Walfrid Ekman, where wind blowing across the ocean surface causes the water to flow, not in the same direction with the wind, but at an angle, as a result of the Coriolis effect.

365 Days of Climate Awareness 115 – The North Pacific Gyre Oscillation
The North Pacific Gyre Oscillation (NPGO) is the oceanic expression of the atmospheric North Pacific Oscillation (NPO), which features seesawing surface air pressures between high (55-65°N) and middle (30-40°N) latitudes in the northeastern Pacific Ocean.

365 Days of Climate Awareness 113 – The North Pacific Oscillation
The North Pacific Oscillation (NPO) is analogous to the North Atlantic Oscillation (NAO), being a variation in surface air pressure between more northerly and more southerly latitudes.

365 Days of Climate Awareness 112 – The North Atlantic Oscillation
The North Atlantic Oscillation (NAO) is a surface atmospheric pressure variation between the Icelandic Low and the Azores High, and controls large-scale weather patterns such as westerly winds and storm tracks across the Atlantic basin.

365 Days of Climate Awareness 110 – The Madden-Julian Oscillation
The Madden-Julian Oscillation (MJO) is a fluctuation in tropical weather, from the upper atmosphere down to surface ocean currents, on the scale of weeks to months which moves east through the Indian and Pacific Oceans.

365 Days of Climate Awareness 109 – The Indian Ocean Dipole
The Indian Ocean Dipole (IOD) is also known as the Indian Niño, because it features the irregular variation of warm and cold sea surface temperatures on the eastern and western regions of the Indian Ocean basin.
