Quarterly Journal of the Royal Meteorological Society, EarlyView.We present a compatible finite‐element discretisation of a general formulation of moist shallow‐water equations, with the aim of providing a simple model to advance understanding of physics–dynamics coupling. We detail set‐ups and show three moist shallow‐water test cases in four different model formulations. The results demonstrate differences between

IEEE Access, 2020 Based on the general relativity theory, the geopotential difference can be determined by comparing the change in time difference between precise clocks using the precise point positioning (PPP) time transfer technique, referred to as the relativistic PPP

A Cut-off low at 500 hPa Geopotential Height and Rainfall Events over Iraq: Case Studies
Iraqi Journal of Physics, 2022 A cut-off low is a closed low with a low value of geopotential height at the upper atmospheric levels that has been fully detached (cut-off) from the westerly flow and move independently. A cut-off low causes extreme rainfall events in the mid-latitudes

The Accuracy Verification of Recent Global Geopotential Model based on GNSS/Levelling Data on Ground Control Points in Johor [PDF]
E3S Web of ConferencesThe external gravitational field of the Earth is mathematically represented using spherical harmonic (SH) coefficients in the global geopotential model. Hence, the appropriate global geopotential model for a region needs to determine a reference surface ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.The ENSO–East Asia teleconnection exhibits strong subseasonal variability, driven by ENSO‐related tropical convection anomalies over the Indian Ocean, Maritime Continent, and central Pacific. GloSea6 fails to accurately predict this teleconnection due to errors in simulating the convection anomalies‐induced teleconnection patterns.

Reanalysis of summer pressure systems affecting Iran\'s atmosphere [PDF]
تحقیقات کاربردی علوم جغرافیایی, 2021 This study investigates the subtropical anticyclones and summer monsoons of the north hemisphere in the 500 hPa level, effective on Iran in a 38-year period (1975-2012).

Longitudinal structure of stationary planetary waves in the middle atmosphere – extraordinary years [PDF]
Annales Geophysicae, 2018 One important but little studied factor in the middle atmosphere meridional circulation is its longitudinal structure. Kozubek et al. (2015) disclosed the existence of the two-cell longitudinal structure in meridional wind at 10 hPa at higher ...
