Climate change is spinning up the global energy and water cycles.

By: Richard Allan I was unfortunate enough to mildly injure my middle finger by typing too frenetically on a train journey from Toulouse returning from an Intergovernmental Panel on Climate Change meeting. I soon forgot about this by luckily stepping … Continue reading

Challenges in the closure of the surface energy budget at the continental scale

By: Bo Dong Since satellite observations began in the late 1970s, our knowledge of energy flows in and out of the Earth’s climate system has been greatly advanced. Taking advantage of state-of-the-art Earth Observation (EO) programmes such as the Clouds … Continue reading

Mapping bio-UV products from space

By: Michael Taylor Solar radiation arriving at the Earth’s surface in the UV part of the spectrum modulates photosynthetically-sensitive life on the land and in the oceans. UV radiation also drives important chemical reaction pathways in the atmosphere that impact … Continue reading

Is it a normal season this year for tropical cyclones in the Western North Pacific?

By Xiangbo Feng  The Western North Pacific (WNP) is the most active area for tropical cyclones (TCs).  The number of TCs occurred in the WNP so far (end of October) this year is 26 – just the average number of … Continue reading

Characteristics and enhanced quality control of drifting buoy observations of sea surface temperature from the International Comprehensive Ocean Atmosphere Data Set (ICOADS)

By Simone Morak-Bozzo Over the last two decades drifting buoys have become the most prevalent in situ measurement method for sea surface temperature(SST). Drifting buoy data are particularly popular because of their high spatial and temporal coverage. Their freedom of … Continue reading

Smoke, science, and sharks

By Ross Herbert In the August of 2017 the Cloud-Aerosol-Radiation Interactions and Forcing – Year 2017 (CLARIFY) measurement campaign took place on a tiny island in the middle of the southeast Atlantic Ocean where we were surrounded by whales, sharks, … Continue reading

Determining the Earth’s energy and water cycles

By Christopher Thomas The Earth’s energy and water cycles govern the distribution and movement of energy and water in the atmosphere, oceans and land. Both energy and water are constantly being transported between different regions of the globe, and the … Continue reading

How the Hadley Cells work

By Gui-Ying Yang The Hadley Cell, named after British meteorologist George Hadley who discovered this tropical atmospheric overturning circulation, is one of the basic concepts in weather and climate. Figure 1 shows the zonal mean overturning circulation in a latitude height … Continue reading

Image conscious atmospheric science

By Giles Harrison A frequently-heard mantra in physics is “Like charges repel and unlike charges attract”. At face value this paraphrase of Coulomb’s Law seems useful for clouds too, as, quite apart from the obvious example of thunderclouds, water drops … Continue reading

Clouds, climate and the Roaring 40s

By Richard Allan In our new research we have traced large and long-standing biases in computer simulations of climate, affecting the tempestuous Southern Ocean, to errors in cloud that emerge rapidly within the atmospheric models. Biases evolve over time through … Continue reading
