Abstract The time variation of a planetary magnetic field can reveal important aspects planet's interior structure. Searching for in fields other than Earth has proved challenging owing to the small number spacecraft missions flown date, but such detection may be possible given sufficiently long baseline comparison. Here we leverage 38 years magnetometer measurements search Saturn’s internal fi...

Observational analysis suggests that the western tropical Pacific (WTP) sea surface temperature (SST) shows predominant variability over multidecadal time scales, which is unlikely to be explained by the Interdecadal Pacific Oscillation. Here we show that this variability is largely explained by the remote Atlantic multidecadal oscillation (AMO). A suite of Atlantic Pacemaker experiments succes...

The growing awareness about the need to anticipate the future of land systems focuses on how well we understand the interactions between society and environmental processes within a complexity framework. A major barrier to understanding is insufficient attention given to long (multidecadal) temporal perspectives on complex system behavior that can provide insights through both analog and evolut...

Coastal foredunes form via biophysical feedbacks between sand accretion and burial-tolerant vegetation can protect coastlines from hazards such as extreme storms sea level rise. Predicting how coastal dunes, the services they provide, will change in future requires an understanding of relative roles physical ecological processes that shape their structure function. Here we assess supply, beach ...

Characteristics of the El Niño–Southern Oscillation (ENSO), such as frequency, propagation, spatial extent, and amplitude, strongly depend on the climatological background state of the tropical Pacific. Multidecadal changes in the oceanmean state are hence likely tomodulate ENSOproperties. To better link background state variations with low-frequency amplitude changes of ENSO, we develop a diag...

[1] We propose a new approach to decompose observed climate variations over the Atlantic Hurricane Basin’s main development region (MDR) into components attributable to radiative forcing changes and to internal oceanic variability. Our attribution suggests that the observed multidecadal anomalies of vertical shear (Uz) and a simple index of maximum potential intensity (SIMPI) for tropical cyclo...

[1] In the interior western United States, increased demand for water coupled with the uncertain nature of anthropogenic and natural hydroclimatic variations add challenges to the task of assessing the adequacy of the existing regional water resources systems. Current availability of relatively short instrumental streamflow records further limits the diagnosis of multidecadal and longer time va...

Recent research suggests a link between drought occurrence in the conterminous United States (US) and sea surface temperature (SST) variability in both the tropical Pacific and North Atlantic Oceans on decadal to multidecadal (D2M) time scales. Results show that the Atlantic Multidecadal Oscillation (AMO) is the most consistent indicator of D2M drought variability in the conterminous US during ...

The sensitivity of Northern Hemisphere sea ice cover to global temperature change is examined in a group of climate models and in the satellite-era observations. The models are found to have well-defined, distinguishable sensitivities in climate change experiments. The satellite-era observations show a larger sensitivity— a larger decline per degree of warming—than any of the models. To evaluat...

We find that summertime air quality in the eastern U.S. displays strong dependence on North Atlantic sea surface temperatures, resulting from large-scale ocean-atmosphere interactions. Using observations, reanalysis data sets, and climate model simulations, we further identify a multidecadal variability in surface air quality driven by the Atlantic Multidecadal Oscillation (AMO). In one-half cy...
