Cut-off lows in the Southern Hemisphere and their extension to the surface
Many cut-off low (COL) climatologies have been done throughout the Southern Hemisphere. Few have focused on COL vertical depth and their link to...

Quantifying rainfall seasonality across South Africa on the basis of the relationship between rainfall and temperature
South Africa spans the subtropics at the interface between tropical, subtropical, and temperate weather systems, and consequently experiences...

A multi-objective paleo-informed reconstruction of western US weather regimes over the past 600 years
Extreme weather variability has long posed difficulties for food, energy, and water systems in the Western US and is only projected to become more...
-
Megadroughts in the Common Era and the Anthropocene
Exceptional drought events, known as megadroughts, have occurred on every continent outside Antarctica over the past ~2,000 years, causing major...

Global increase in wildfire potential from compound fire weather and drought
Wildfire can cause significant adverse impacts to society and the environment. Weather and climate play an important role in modulating wildfire...

Impact of Warm Winters on the White Sea: In Silico Experiment
We use the numerical model JASMINE for the in silico experiment on the White Sea by estimating the influence of two warm winters on water...
-
Four distinct Northeast US heat wave circulation patterns and associated mechanisms, trends, and electric usage
Northeastern US heat waves have usually been considered in terms of a single circulation pattern, the high-pressure circulation typical of most heat...

Causal oceanic feedbacks onto the winter NAO
Of the climate variability patterns that influence the weather in the North Atlantic region in winter, the North Atlantic Oscillation (NAO) is the...

Representation of sea ice regimes in the Western Ross Sea, Antarctica, based on satellite imagery and AMPS wind data
Sea ice drift data at high spatial resolution and surface wind model output are used to explore atmosphere-sea ice interactions in the Western Ross...

Combined large-scale tropical and subtropical forcing on the severe 2019–2022 drought in South America
Changes in the frequency and magnitude of dry spells have been recorded over the past few decades due to an intensification of the global water...

Atmospheric blocking events in the North Atlantic: trends and links to climate anomalies and teleconnections
Atmospheric blockings are generally associated with large-scale high-pressure systems that interrupt west-to-east atmospheric flow in mid and high...

Mechanics of Lake Ice
Ice in the Earth’s nature is mechanically complex medium as its properties depend on the space and time scales. In short-term loading ice is elastic,...

Interannual variability of East African rainfall: role of seasonal transitions of the low-level cross-equatorial flow
During boreal spring and fall, the low-level cross-equatorial flow along the East African coast weakens and reverses. These transition periods are...

Drought in the Eastern Cape region of South Africa and trends in rainfall characteristics
Much of the Eastern Cape province in South Africa has been experiencing a severe drought since 2015. This drought has had major socio-economic...

Observed relationship between the Turkana low-level jet and boreal summer convection
The Turkana low-level jet is a circulation feature over northern Kenya that is not spatially well-resolved in many observational datasets. Here,...

The Cape Town “Day Zero” drought and Hadley cell expansion
In early 2018, Cape Town (population ~3.7 million) was at risk of being one of the first major metropolitan areas in the world to run out of water....

Influence of Arctic sea-ice loss on the Greenland ice sheet climate
The Arctic is the region on Earth that is warming the fastest. At the same time, Arctic sea ice is reducing while the Greenland ice sheet (GrIS) is...

Monitoring Earth’s climate variables with satellite laser altimetry
Satellite laser altimetry measures accurate elevations of the Earth’s surface and precise changes with time, monitoring key climate variables. These...

Patterns of atmospheric circulation in Western Europe linked to heavy rainfall in Germany: preliminary analysis into the 2021 heavy rainfall episode
The July 2021 heavy rainfall episode in parts of Western Europe caused devastating floods, specifically in Germany. This study examines circulation...

A quasi-geostrophic diagnosis of the zonal flow associated with cut-off lows over South Africa and surrounding oceans
The zonal flow associated with cut-off lows (COLs) comprises two jet streaks of different spatial extents. The smaller scale jet streak, located...
