BoBBLE: Air-sea interactions and intraseasonal oscillations in the Bay of Bengal

By Simon Peatman The Indian Summer Monsoon (ISM) is one of the most significant features of the tropical climate. The heavy rain it brings during boreal summer provides around 80% of the annual precipitation over much of India with over 1 … Continue reading

Time scales of atmospheric circulation response to CO2 forcing

By Paulo Ceppi An important question in current climate change research is, how will atmospheric circulation change as the climate warms? When simulating future climate scenarios, models commonly predict a shift of the midlatitude circulation to higher latitudes in both … Continue reading

Soil Moisture retrieval from satellite SAR imagery

By Keith Morrison Soil moisture retrieval from satellite synthetic aperture radar (SAR) imagery uses the knowledge that the signal reflected from a soil is related to its dielectric properties. For a given soil type, variations in dielectric are controlled solely … Continue reading

It melts from the top too …

By David Ferreira The global sea level rises at about 3 mm/year. Oceans absorb nearly 90% of the heat trapped in the atmosphere by anthropogenic gases like carbon dioxide. As water warms, it expands: this effect explains about half of … Continue reading

Reducing climate change from aviation: could climate-friendly routing play a part?

By Emma Irvine It’s commonly known that burning fossil fuels, like in jet engines, leads to the emission of carbon dioxide (CO2) which causes global warming. It is perhaps less well known that, particularly in the case of aviation, carbon … Continue reading

Why has there been a rapid increase in heat-related extremes in Western Europe since the mid-1990s?

By Buwen Dong In the last few decades, Europe has warmed not only faster than the global average, but also faster than expected from anthropogenic greenhouse gas increases (van Oldenborgh et al., 2009). With the warming, Europe experienced record-breaking heat … Continue reading

Changing wet and dry seasons

By Richard Allan The fickle nature of weather patterns is ultimately responsible for the where and when of tropical rainfall extremes which wreak damage on agriculture, infrastructure and people. Tropical cyclones, such as Enawo which battered Madagascar in March, can … Continue reading

Potential links between Arctic sea ice loss and mid-latitude weather: revisiting an influential earlier study

by Len Shaffrey The Arctic is changing rapidly due to human emissions of greenhouse gases. Arctic sea ice extent has been declining by 12% per decade since reliable satellite estimates began in 1979. By summer 2012, Arctic sea ice extent … Continue reading

Water vapour transport by tropical cyclones over East Asia

By Liang Guo When talking about tropical cyclones (TCs), people tend to think about gusty winds and heavy rain. These weather phenomena impress us due to the immense impacts on our surroundings. However, these weather phenomena are short-lived. Most TCs … Continue reading
