Investigation of ENSO variability using cyclostationary EOFs of observational data
Meteorology and Atmospheric Physics - Tập 81 - Trang 149-168 - 2002
K.-Y. Kim
¶The variability of El Niño-Southern Oscillation (ENSO) on all time scales, ranging from months to decades, has been studied from the perspective of sea-surface temperature anomaly (SSTA), sea-level pressure anomaly (SLPA), and surface wind anomaly (SWA) fields using a statistical tool called cyclostationary empirical orthogonal function (CSEOF) analysis. The analysis indicates that a significant ...... hiện toàn bộ
A Chebyshev spectral method for boundary-layer models
Meteorology and Atmospheric Physics - Tập 33 - Trang 117-126 - 1984
W. H. Schubert, G. D. Taylor, S. R. Fulton, M. DeMaria
Boundary-layers in the atmosphere and ocean often take on the structure of mixed layers bounded by narrow, highly stable regions. Simulation of the movement of such stable regions is a challenging task for the numerical modeler. Here we explore the use of Chebyshev spectral methods. We compare the results of spectral and finite difference methods for a simple one-dimensional test problem with know...... hiện toàn bộ

Numerical experiments investigating the orographic effects on a heavy rainfall event over the northwestern coast of Taiwan during TAMEX IOP 13
Meteorology and Atmospheric Physics - Tập 114 - Trang 35-50 - 2011
Pay-Liam Lin, Yi-Leng Chen, Ching-Sen Chen, Che-Ling Liu, Ching-Ying Chen
An unusual heavy coastal rainfall event (>231 mm day−1) occurred during the period of 24–25 June 1987 over the lowland (elevation less than 200 m) and coastal areas in northwest and central Taiwan. The Weather Research and Forecasting (WRF) model is used to investigate the role of synoptic forcing, orographic effects and the diurnal heating cycle on the generation of a prefrontal localized low-lev...... hiện toàn bộ
The impact of spatial and temporal distribution of satellite observations on tropical cyclone data assimilation: Preliminary results
Meteorology and Atmospheric Physics - Tập 60 - Trang 157-163 - 1996
J. F. Le Marshall, L. M. Leslie, C. Spinoso
Preliminary work gauging the impact of varying the spatial and temporal resolution of Cloud Drift Wind (CDW) data using different assimilation techniques is presented, particularly within the framework of a generalised inverse data assimilation scheme. Results are presented for the NW Pacific and Australian regions. There were three main findings for the cases examined. Firstly, hourly and 12-hour...... hiện toàn bộ
Characteristics of various radiative fluxes: global, tilted, direct, and diffused radiation—a case study of Nigeria
Meteorology and Atmospheric Physics - Tập 135 Số 2 - 2023

Bemerkungen zur Frage der Sicht in Wolken
Meteorology and Atmospheric Physics - - 1960
R. Trappenberg
Theoretisch ist aus Messungen der Größenverteilung von Wolkenelementen mit Hilfe derMieschen Theorie die Berechnung der Sichtweite in Wolken möglich; dabei wird die Absorption im allgemeinen als vernachlässigbar klein angesehen. An über 300 in Wolken gemessenen Spektren der Häufigkeitsverteilung der Sicht wird diese Rechnung durchgeführt und mit den gleichzeitig gemessenen bzw. geschätzten Sichtwe...... hiện toàn bộ
Föhnentwicklung durch Höhentiefdruckgebiete
Meteorology and Atmospheric Physics - Tập 2 - Trang 82-96 - 1949
H. Hoinkes
Der zwischen dem 2. und 4. Oktober 1941 in den nördlichen Alpentälern beobachtete Südföhn ist aus den in der Bodenwetterkarte ersichtlichen Luftdruckgradienten nicht zu verstehen. Er verdankt seine Entstehung einem kleinen abgeschlossenen Höhentief, das auf die mittleren Schichten der Troposphäre beschränkt ist, in dessen Strömungsbereich sich der Alpenkamm in den genannten Tagen befindet. Die wäh...... hiện toàn bộ
A study of rapid intensification of tropical cyclone Ockhi using C-band polarimetric radar
Meteorology and Atmospheric Physics - Tập 134 - Trang 1-23 - 2022
Sambit Kumar Panda, Anup Kumar Mandal, Bipasha Paul Shukla, Neeru Jaiswal, Chandra Mohan Kishtawal, Atul Kumar Varma
Tropical cyclone Ockhi (2017) had a very unusual track with unprecedented rapid intensification (RI) and dynamical evolution. During its early phases, a C-band polarimetric Doppler Weather Radar (DWR), installed in Thiruvananthapuram, Kerala, continuously monitored it. The present study focuses on the observations and analysis of the extremely tall precipitation features overshooting Troposphere, ...... hiện toàn bộ
The influence of geometry on recirculation and CO2 transport over forested hills
Meteorology and Atmospheric Physics - Tập 119 - Trang 187-196 - 2012
Xiyan Xu, Chuixiang Yi
Flow distortion over a forested hill is asymmetric, forming a recirculation region on the lee slope that increases the complexity in understanding atmosphere–biosphere interaction. To understand the complexity, we examine the effect of the geometry of forested hills on recirculation formation, structure, and related CO2 transport by performing numerical simulations over double-forested hills. The ...... hiện toàn bộ
