Moist convection and radiative cooling: Dynamical response and scaling

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The mechanism that sets the updraught velocities in deep convective clouds is studied here using cloud‐resolving model simulations in radiative–convective equilibrium. We show that, for simulations with vastly different rates of radiative cooling and surface temperatures, the buoyancy in clouds remains remarkably constant (histogram shown here).

The stratospheric gravity wave field produced by a supercell

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Supercells are a class of long‐lasting thunderstorms with rotating updrafts that often cause severe weather, hail, and tornadoes. This study uses numerical simulations to characterize the stratospheric gravity waves that are caused by these storms.

When tiny convective spread affects a midlatitude jet: Spread sequence

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We investigate spread evolution by mesoscale convection from tiny initial condition uncertainty during a real event. There is significant variation among the systems in their propensity to interact with the jet stream, whereby variability in one system (due to convective and long‐wave radiative heating tendencies) tightly relates to Rossby‐like ...

Mesoscale dynamics of cyclone Leslie (2018): A diagnostic analysis of a rare Iberian landfall

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study presents a successful numerical simulation of cyclone Leslie (2018), using WRF‐ARW v4.5.1. Several mesoscale dynamics were identified indicative of the occurrence of sting jet and cold conveyor belt, which potentiated the record‐breaking winds in central Portugal.

Exploration of the use of short‐wave infrared radiances in weather forecasts model Part II: Data assimilation and forecast impact assessment

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The standalone non‐local thermodynamic equilibrium (NLTE) bias correction schemes, utilizing a look‐up‐table and a linear regression method developed in Part I and new quality control procedures for short‐wave infrared radiances (SWIR), were tested within a data assimilation framework.

A case study of temperature tendency mechanisms operating over northern Africa during and following midlatitude winter troughs

Quarterly Journal of the Royal Meteorological Society, EarlyView.
An Iberia‐Central Mediterranean trough sequence (7–10 February 2018) delivers anomalous low‐level temperature tendencies attributable to dynamics across most of northern Africa, with warming over northeastern Africa, especially 10–12 February into the eastern Sahel. An ECMWF product attributes the tendencies (see Figure).

Physically consistent mesoscale model evaluation in complex terrain

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study introduces a novel approach for evaluating mesoscale atmospheric models in complex terrain by selecting physically consistent grid points and applying height‐based corrections. The method corrects for sensor height and terrain elevation differences between model and observations using a time‐varying lapse rate.

Study of the flood in Golestan province from a statistical and synoptics point of view (Case study: March 2019) [PDF]

تحقیقات کاربردی علوم جغرافیایی
Flood is one of the most destructive natural phenomena. Every year it brings extensive losses to the country’s financial and human resources. In our country, major parts of Iran’s provinces are always at risk of flooding.
