What caused the cool summer over northern Central Asia, East Asia and central North America during 2009?

open access: yesEnvironmental Research Letters, 2012
Cool and wet weather conditions hit northern Central Asia, East Asia and central North America during the 2009 summer in concert with a strong jet stream and a prominent meandering upper-level circulation in the Northern Hemisphere mid-latitudes despite ...

Interannual variation of the Warm Arctic–Cold Eurasia pattern modulated by Ural blocking and the North Atlantic Oscillation under changing sea ice conditions

open access: yesProgress in Earth and Planetary Science, 2023
Together with rapid Arctic warming and sea ice decline, especially over the Barents–Kara seas (BKS), extreme cold winters have occurred frequently in mid-latitudes, particularly in Central Eurasia. A pattern with two distinct winter temperature anomalies

Atmospheric Circulation Regimes in a Nonlinear Quasi-Geostrophic Model

open access: yesAdvances in Meteorology, 2015
Atmospheric low-frequency variability and circulation regime behavior are investigated in the context of a quasi-geostrophic (QG) three-level T63 model of the wintertime atmospheric circulation over the Northern Hemisphere (NH).

The single beacon: progresses in understanding Earth as an exoplanet using DSCOVR/EPIC observations

open access: yesFrontiers in Remote Sensing
Almost 6000 exoplanets have thus far been confirmed, revolutionizing our understanding of planetary habitability. Yet, despite the identification of Earth-like exoplanets, definitive evidence of extraterrestrial life remains elusive.

Atmospheric QBO and ENSO indices with high vertical resolution from GNSS radio occultation temperature measurements [PDF]

open access: yesAtmospheric Measurement Techniques, 2018
We provide atmospheric temperature variability indices for the tropical troposphere and stratosphere based on global navigation satellite system (GNSS) radio occultation (RO) temperature measurements. By exploiting the high vertical resolution and the

Chaotic Variability of Ocean Heat Content: Climate-Relevant Features and Observational Implications

open access: yesOceanography, 2018
Global ocean models that admit mesoscale turbulence spontaneously generate interannual-to-multidecadal chaotic intrinsic variability in the absence of atmospheric forcing variability at these timescales.

Decadal variability and trends of the Benguela upwelling system as simulated in a high-resolution ocean simulation [PDF]

open access: yesOcean Science, 2015
Detecting the atmospheric drivers of the Benguela upwelling systems is essential to understand its present variability and its past and future changes.

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Tomography of the Atmosphere of the Mira Variable Z Oph [PDF]

open access: yesInternational Astronomical Union Colloquium, 2002
AbstractThe new tomographic technique devised by Alvarez et al. (2000) to explore the velocity field across the atmosphere of long-period variable stars (LPVs) is applied to the Mira variable Z Oph. The method cross-correlates the optical spectrum with numerical masks constructed from synthetic spectra and probing layers of increasing depths.
