Sudden stratospheric warmings (SSWs) are impressive fluid dynamical events in which
large and rapid temperature increases in the winter polar stratosphere (∼ 10–50 km) are …

Since its discovery in the early 1970s, the crucial role of the Madden‐Julian Oscillation
(MJO) in the global hydrological cycle and its tremendous influence on high‐impact climate …

There is high demand and a growing expectation for predictions of environmental conditions
that go beyond 0–14-day weather forecasts with outlooks extending to one or more seasons …

The stratosphere can have a significant impact on winter surface weather on subseasonal to
seasonal (S2S) timescales. This study evaluates the ability of current operational S2S …

A minor sudden stratospheric warming (SSW) happened in September 2019 in the Southern
Hemisphere (SH) with winds at 10 hPa, 60° S reaching their minimum value on 18 …

Sudden stratospheric warmings (SSWs) are significant source of enhanced subseasonal
predictability, but whether this source is untapped in operational models remains an open …
