Intensification of Near‐Surface Currents and Shear in the Eastern Arctic Ocean
(Journal article; Peer reviewed, 2020)A 15‐year (2004–2018) record of mooring observations from the upper 50 m of the ocean in the eastern Eurasian Basin reveals increased current speeds and vertical shear, associated with an increasing coupling between wind, ... -
Intensified Impacts of Central Pacific ENSO on the Reversal of December and January Surface Air Temperature Anomaly over China since 1997
(Journal article; Peer reviewed, 2021)The reversal of surface air temperature anomalies (SATA) in winter brings a great challenge for short-term climate prediction, and the mechanisms are not well understood. This study found that the reversal of SATA between ... -
An Intensity and Size Phase Space for Tropical Cyclone Structure and Evolution
(Journal article; Peer reviewed, 2023)Intensity and size are important to characterize a tropical cyclone (TC), but there are a wide variety of ways that both metrics are defined. TC intensity can refer to either a maximum sustained wind speed at some height ... -
Interannual controls on Weddell Sea surface water fCO2 during the autumn–winter transition phase
(Peer reviewed; Journal article, 2004-06)The fugacity of carbon dioxide (fCO2) of the surface waters of the Weddell Sea along the prime meridian has been described for the austral autumn in 1996 and 1998. For individual years, fCO2 has a strong linear relationship ... -
Interannual sea-air CO2 flux variability from an observation-driven ocean mixed-layer scheme
(Peer reviewed; Journal article, 2014-09-01)Interannual anomalies in the sea–air carbon dioxide (CO2) exchange have been estimated from surface-ocean CO2 partial pressure measurements. Available data are sufficient to constrain these anomalies in large parts of the ... -
Interannual variability and ventilation timescales in the ocean cavity beneath Filchner-Ronne Ice Shelf, Antarctica
(Peer reviewed; Journal article, 2004-04-20)Multiyear time series of ocean current and temperatures from beneath Filchner-Ronne Ice Shelf, Antarctica, demonstrate both seasonal and interannual variability. The seasonal signal is visible at all measurement sites, ... -
Interannual variability in the wintertime air–sea flux of carbon dioxide in the northern North Atlantic, 1981–2001
(Peer reviewed; Journal article, 2003)Gridded fields of sea surface temperature (SST), sea level pressure (SLP), and wind speed were used in combination with data for the atmospheric mole fraction of CO2 and an empirical relationship between measured values ... -
Interannual variability of air temperature inversions in ice-free area of northern James Ross Island, Antarctica
(Journal article; Peer reviewed, 2022)Air temperature inversions are common features in Antarctica, especially in the interior where they are observed nearly year-round. Large temporal variability of air temperature inversion incidence is typical for the coastal ... -
Interannual variations of freshwater content in Hornsund
(Master thesis, 2015-05-04)Salinity measurements have been used to calculate the freshwater content in Hornsund for the years 2001 to 2014. In 2011 there was significantly higher freshwater content in the fjord, compared to the other years, with a ... -
Intercomparison of Small Unmanned Aircraft System (sUAS) Measurements for Atmospheric Science during the LAPSE-RATE Campaign
(Peer reviewed; Journal article, 2019-05-10)Small unmanned aircraft systems (sUAS) are rapidly transforming atmospheric research. With the advancement of the development and application of these systems, improving knowledge of best practices for accurate measurement ... -
Interdecadal Changes in the Linkage Between North Pacific Oscillation During May and Northeast China Precipitation During Mid-Summer: The Influence of North Atlantic Oscillation
(Journal article; Peer reviewed, 2023)Many previous studies have documented the relationship between the North Pacific Oscillation (NPO) and the weather/climate of upstream and downstream regions. However, the stability of NPO precursor signals of East Asian ... -
Intermediate water from the Greenland Sea in the Faroe Bank Channel : spreading of released sulphur hexafluoride
(Journal article, 2005-02)The Faroe Bank Channel is the deepest passage for dense water leaving the Nordic Seas into the North Atlantic. The contribution to this part of the Greenland-Scotland Overflow by intermediate water from the Greenland Sea ... -
Intermittency of Arctic–mid-latitude teleconnections: stratospheric pathway between autumn sea ice and the winter North Atlantic Oscillation
(Journal article; Peer reviewed, 2020)There is an observed relationship linking Arctic sea ice conditions in autumn to mid-latitude weather the following winter. Of interest in this study is a hypothesized stratospheric pathway whereby reduced sea ice in the ... -
Intermittent Reduction in Ocean Heat Transport Into the Getz Ice Shelf Cavity During Strong Wind Events
(Journal article; Peer reviewed, 2021)The flow of warm water toward the western Getz Ice Shelf along the Siple Trough, West Antarctica, is intermittently disrupted during short events of Winter Water deepening. Here we show, using mooring records, that these ... -
Intraseasonal and synoptic modulation of diurnal surface solar radiation over Reunion island in the South-West Indian Ocean
(Journal article; Peer reviewed, 2023)Understanding the space-time variability of Surface Solar Radiation (SSR) is mandatory for the prediction and, eventually, the skillful forecasting of photovoltaic energy production. This paper addresses the modulation of ... -
Introduction to focus issue: Synchronization in large networks and continuous media - Data, models, and supermodels
(Peer reviewed; Journal article, 2017)The synchronization of loosely coupled chaotic systems has increasingly found applications to large networks of differential equations and to models of continuous media. These applications are at the core of the present ... -
