Diagnostics of the tropical tropopause layer from in-situ observations and CCM data [PDF]

, 2009
A suite of diagnostics is applied to in-situ aircraft measurements and one Chemistry-Climate Model (CCM) data to characterize the vertical structure of the Tropical Tropopause Layer (TTL).

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.

Assessing high‐resolution numerical models and bottom‐boundary factors for a Mediterranean heavy precipitation event

Quarterly Journal of the Royal Meteorological Society, EarlyView.
State‐of‐the‐art, convection‐permitting NWP models reproduced the main features of the October 22–23, 2019 heavy precipitation event in Catalonia. However, slight configuration changes yielded varying streamflow responses and statistical performance, highlighting the challenge of simulating these events in Mediterranean medium‐sized basins ...

Three-dimensional distribution of nonmenthane hydrocarbons and halocarbons over the northwestern Pacific during the 1991 Pacific Exploratory Mission (PEM-West A) [PDF]

, 1996
A total of 1667 whole air samples were collected onboard the NASA DC-8 aircraft during the 6-week Pacific Exploratory Mission over the western Pacific (PEM-West A) in September and October 1991.

Indian and African monsoons: Trajectories and interactions

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The catch basin of marine air particles of the Indian monsoon is the tropical Indian ocean, whilst that of the African monsoon is the east tropical Atlantic. However, the oscillations induced by the monsoonal interactions favour particle exchange between the two basins. These transitions are abrupt in the presence of stochastic resonance. The monsoonal

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).

Sensitivity of flower trade‐wind cloud organisation to mesoscale atmospheric heterogeneities

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Trade‐wind cloud organisation is insensitive to dynamical and thermal heterogeneities but very sensitive to humidity mesoscale heterogeneities, especially in the cloud layer, where they form moist patches, and not in the sub‐cloud layer. Clouds and rain develop in moist patches, then cold pools develop progressively, initiating mesoscale circulations ...

Ray Tracing and Applications to an Evaporation Duct Model Based on Data from Oceanographic Buoy Sensors

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
The two-dimensional ray tracing method allows an easy and fast modeling of tropospheric propagation in the microwave frequency range. A version of this method that determines ray trajectories, amplitudes and delays of the electromagnetic field, as well ...

The characteristics of squall lines in the Southeast Asia region

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Squall lines over the Maritime Continent were analysed using 20 years of IMERG GPM data and classified into four regional clusters. Significant regional differences were found in their size, intensity, lifespan, and propagation. Nighttime squall lines are primarily driven by the convergence of opposing offshore flows and the convergence of monsoonal ...

The non‐hydrostatic option of the ECMWF global weather forecast model: Improvements for kilometre‐scale modelling

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study presents improvements to the non‐hydrostatic version of the European Centre for Medium‐Range Weather Forecasts (ECMWF) Integrated Forecasting System (IFS), enabling stable global simulations at 1.4‐km resolution. A systematic comparison with the hydrostatic version at resolutions from 9 to 1.4 km shows that non‐hydrostatic effects emerge in ...
