Rain storm models and the relationship between their parameters [PDF]
Rainfall interstation correlation functions can be obtained with the aid of analytic rainfall or storm models. Since alternative storm models have different mathematical formulas, comparison should be based on equallity of parameters like storm diameter,

Quarterly Journal of the Royal Meteorological Society, EarlyView.Key Findings: An assimilation methodology is established for the Tomorrow.io microwave sounder (TMS) flying on CubeSats in sun‐synchronous and inclined orbits, and in all cloud scenes. The TMS has a significant impact on weather forecast lead times up to 3 days in the Tropics in a research‐quality numerical weather prediction setting, and yields water ...

Geophysical Research LettersIn autumn 2024 (late October to mid‐November), an unprecedented multiple tropical cyclone (MTC) event occurred over the western North Pacific (WNP). Six storms formed within a month, surpassing the climatological mean by 4 standard deviations.

Quarterly Journal of the Royal Meteorological Society, EarlyView.This study investigates year‐round exceptionally poor and good day‐6 forecasts of the 500‐hPa geopotential height field over Europe using 45 years of ERA5 reforecasts and applies a weather regime perspective to analyse large‐scale pattern evolution and regime transitions.

The connection between North Atlantic storm track regimes and eastern Mediterranean cyclonic activity [PDF]
Weather and Climate DynamicsA unique chain connects the flow over the North Atlantic and the development of cyclones within the Mediterranean basin. One typical mechanism includes several successive processes: upper-level flow perturbations upstream cause Rossby wave breaking (RWB)

An instance of cyclonic upwelling in the southern offshore waters of Lake Victoria [PDF]
, 1971 Evidence is presented that cyclonic upwelling took place in the southern offshore waters of Lake Victoria on the 22nd to the 23rd March, 1969. Before this, the main upper thermocline was tilted downwards in the leeward northern half of the lake in ...

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.

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.
