Intraseasonal Oscillation of Summer Extreme High Temperature in Northeast China and Associated Atmospheric Circulation Anomalies

Atmosphere, 2022
Previous studies have demonstrated the important effects of intraseasonal oscillations in the tropics on the occurrence of extreme-high-temperature events (EHTs), whereas the influence of intraseasonal oscillations in mid-high latitudes on EHTs has been ...

A multiscale model for tropical intraseasonal oscillations [PDF]

Proceedings of the National Academy of Sciences, 2004
The tropical intraseasonal 40- to 50-day oscillation (TIO) is the dominant component of variability in the tropical atmosphere with remarkable planetary-scale circulation generated as envelopes of complex multiscale processes. A new multiscale model is developed here that clearly demonstrates the fashion in which planetary-scale circulations sharing ...

Intraseasonal oscillations of stratospheric ozone above Switzerland [PDF]

Journal of Atmospheric and Solar-Terrestrial Physics, 2012
Abstract GROMOS, the ground-based millimeter-wave ozone spectrometer, continuously measures the stratospheric ozone profile between the altitudes of 20 and 65 km above Bern ( 46 ° 57 ′ N , 7 ° 27 ′ E ) since November 1994. Characteristics of intraseasonal oscillations of stratospheric ozone are derived from the long-term data set ...

Predictability Limit of Monsoon Intraseasonal Precipitation: An Implication of Central Indian Ocean Mode

Frontiers in Marine Science, 2022
The prediction of monsoonal precipitation during Indian summer monsoon (ISM) remains difficult. Due to the high correlation between the Central Indian Ocean (CIO) mode index and the ISM precipitation variability, the predictability limit of the CIO mode ...

The intraseasonal fluctuation of Indian summer monsoon rainfall and its relation with monsoon intraseasonal oscillation (MISO) and Madden Julian oscillation (MJO) [PDF]

Theoretical and Applied Climatology, 2021
Abstract The intra-seasonal fluctuations of Indian summer monsoon rainfall (ISMR) are mainly controlled by northward propagating Monsoon Intra-seasonal Oscillation (MISO) and eastward propagating Madden Julian Oscillation (MJO). In the current study, we examine the relationship between the intra-seasonal fluctuations (active and break spells ...

Impact of Intraseasonal Oscillations on the Activity of Tropical Cyclones in Summer Over the South China Sea: Nonlocal Tropical Cyclones

Frontiers in Earth Science, 2020
In addition to tropical cyclones (TCs) locally formed in the South China Sea (SCS), there are also TCs that initially form over the Northwest Pacific (NWP) and move westward to enter the SCS (often called nonlocal TCs).

A simple model of intraseasonal oscillations [PDF]

Journal of Advances in Modeling Earth Systems, 2017
AbstractThe intraseasonal oscillations and in particular the MJO have been and still remain a “holy grail” of today's atmospheric science research. Why does the MJO propagate eastward? What makes it unstable? What is the scaling for the MJO, i.e., why does it prefer long wavelengths or planetary wave numbers 1–3?

Intraseasonal Variability in an Aquaplanet General Circulation Model

Journal of Advances in Modeling Earth Systems, 2010
An aquaplanet atmospheric general circulation model simulation with a robust intraseasonal oscillation is analyzed. The SST boundary condition resembles the observed December-April average with continents omitted, although with the meridional SST ...

Improving Real-Time Forecast of Intraseasonal Variabilities of Indian Summer Monsoon Precipitation in an Empirical Scheme

Frontiers in Earth Science, 2020
In contrast to the historical forecast test which is temporally successive with a near-steady forecast skill, the real-time forecast made at any one moment produces a forecast time-series whose skill rapidly decreases as the forecast lead time increases;

Tropical and mid-latitude teleconnections interacting with the Indian summer monsoon rainfall: a theory-guided causal effect network approach [PDF]

Earth System Dynamics, 2020
The alternation of active and break phases in Indian summer monsoon (ISM) rainfall at intraseasonal timescales characterizes each ISM season. Both tropical and mid-latitude drivers influence this intraseasonal ISM variability.
