Robust signatures of solar neutrino oscillation solutions
With the goal of identifying signatures that select specific neutrino oscillation parameters, we test the robustness of global oscillation solutions that fit all the available solar and reactor experimental data. We use three global analysis strategies previously applied by different authors and also determine the sensitivity of the oscillation solutions to the critical nuclear fusion cross sec...
متن کاملTemperature response of Earth to the annual solar irradiance cycle
We directly determine the sensitivity and time delay of Earth’s surface temperature response to annual solar irradiance variations from 60 years of data. A two-layer energy balance model is developed to interpret the results. Explaining both the resulting low sensitivity and time delay of 1–2 months requires negative feedback. 2004 Elsevier B.V.

متن کاملIs the stratospheric quasi‐biennial oscillation affected by solar wind dynamic pressure via an annual cycle modulation?
[1] In this study, statistical evidence of a possible modulation of the equatorial stratospheric quasi‐biennial oscillation (QBO) by the solar wind dynamic pressure is provided. When solar wind dynamic pressure is high, the QBO at 30–70 hPa is found to be preferably more easterly during July–October. These lower stratospheric easterly anomalies are primarily linked to the high‐frequency compone...
متن کاملOn the Annual Cycle of Upper-Ocean Circulation in the Eastern Equatorial Pacific
An oceanic general circulation model is used to investigate the annual cycle of the near-surface currents in the eastern equatorial Pacific Ocean; in particular, the causes of the springtime increase of eastward momentum that reverses the westward surface flow and intensifies the Equatorial Undercurrent are examined. A set of process experiments are carried out that isolates effects due to thre...
متن کاملA combination mode of the annual cycle and the El Niño/Southern Oscillation
The El Niño/Southern Oscillation (ENSO) is characterized by two main states: El Niño events defined by positive sea surface temperature anomalies in the eastern tropical Pacific Ocean and La Niña events marked by cooler surface temperatures in the same region. ENSO is broadly considered to be an oscillatory instability of the coupled ocean–atmosphere system in the tropical Pacific1–6 that shows...
