Covariance of the intertropical discontinuity and African easterly jet in Sahelian wet and dry years

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Intertropical discontinuity and African easterly jet (AEJ) positions are strongly correlated, with a more pronounced linear relationship across wet years. Surface heat flux anomalies modify low‐level temperature and sensible heat flux gradients that shift the AEJ core south of the gradient maxima in both composites.

Capturing dense shelf water cascading with a high-resolution ocean reanalysis [PDF]

Ocean Science
Abstract. Dense shelf water cascading (DSWC) is an oceanographic process that occurs when dense shelf water overflows over the shelf edge downslope toward the deep sea. Monitored in the northwestern Mediterranean by moorings since 1993 in the Lacaze-Duthiers Canyon and since 2005 in the Cap de Creus Canyon, numerical modeling with reanalysis extends ...

An Ocean Reanalysis System for the Joining Area of Asia and Indian-Pacific Ocean

Atmospheric and Oceanic Science Letters, 2010
AbstractAn ocean reanalysis system for the joining area of Asia and Indian-Pacific Ocean (AIPO) has been developed and is currently delivering reanalysis data sets for study on the air-sea interaction over AIPO and its climate variation over China in the inter-annual time scale.

Does vertical wind shear increase tropical cyclone rain?

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A 26‐year modern precipitation dataset is used to systematically assess tropical cyclone (TC) rainfall responses to vertical wind shear (VWS). VWS enhances rainfall volume in TCs by up to 23%, despite reducing storm intensity, revealing a trade‐off where VWS mitigates wind damage but potentially amplifies flood risk.

Moisture and wind effects of Rossby waves on Western Pacific Intertropical Convergence Zone breakdown events

Quarterly Journal of the Royal Meteorological Society, EarlyView.
(a) Organized convection: clouds are clustered at the southern edge of the domain, aligning with the warmest SST. Northeasterly winds prevail, facilitating convection confinement to the southern part of the domain. (b) ITCZ breakdown: the clouds are spread throughout the domain.

METEOROLOGICAL DATA ANALYSIS THROUGHOUT THE OCEAN PACIFIC MEXICAN COAST (CLIMATOLOGY: PART I)

Ra Ximhai, 2017
Time series obtained by reanalysis are analyzed in different zones of the Pacific Ocean Mexican coast, in order to obtain climatology. The results indicate that they are related to local conditions and to the ocean-atmosphere interaction on the coast.

Spatial and temporal variability of wet spells and their role in wet and dry summers and winters in Australia

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The change in the frequency of wet spells in tropical Australia in summer primarily contributes to the change in precipitation between wet and dry years. In the extratropics, both the frequency and intensity of wet spells are important, especially in winter.

Inertia-induced accumulation of flotsam in the subtropical gyres

, 2016
Recent surveys of marine plastic debris density have revealed high levels in the center of the subtropical gyres. Earlier studies have argued that the formation of great garbage patches is due to Ekman convergence in such regions.

The relationship between seasonal mean temperature and most extreme day

Quarterly Journal of the Royal Meteorological Society, EarlyView.
In Northern Hemisphere winter, there is a strong correlation between seasonal mean temperature and coldest daily mean temperature which varies in magnitude from one region to another (with a weaker relationship in summer between mean and hottest day).

Diagnostic Method for Atmosphere–Ocean Coupling Over Tropical Oceans at the Sub‐Seasonal Timescale

Geophysical Research Letters
This study introduces a novel diagnostic method to assess tropical atmosphere‐ocean coupling, using a two‐dimensional plane defined by the 90‐day high‐pass‐filtered sea surface temperature (SST) and column water vapor (CWV).
