Eastward Propagation of Anomalous Indo–Pacific Walker Circulation During ENSO Transition

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract By analyzing the zonal mass streamfunction over the equatorial Indo–Pacific region in the period 1979–2024, we found that during the decaying phase of 13 out of 31 El Niño‐Southern Oscillation (ENSO) events, the anomalous Indo–Pacific Walker Circulation (IPWC) propagates steadily eastward across the warm pool. Vertical velocity, precipitation,

Influence of the Madden-Julian Oscillation on upper tropospheric humidity [PDF]

, 2002
Variations of upper tropospheric humidity (UTH) and cold cloud in the tropics reveal coherent changes that propagate eastward from the Indian Ocean into the Pacific. The coherence of UTH is high at periods of 30–90 days along the equator.

Maintenance of Moisture Anomalies Across Synoptic and Intraseasonal Timescales Over the Indo‐Pacific Warm Pool

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Moisture variability plays a fundamental role in regulating tropical precipitation; however, the mechanisms that sustain moisture anomalies across different timescales remain unclear. This study examines how moisture anomalies are regulated over the Indo‐Pacific warm pool using the column‐integrated moist static energy (CMSE) budget.

Quasi-biweekly oscillations and midlatitude wave-train modulation of intraseasonal temperature variability over Tanzania during OND

Discover Atmosphere
Intraseasonal variability strongly influences East African climate, yet its impact on near-surface temperature has received limited attention compared to rainfall.

Intraseasonal variability in South America during the cold season

Climate Dynamics, 2013
Intraseasonal (IS) variability in South America is analyzed during the cold season using 10–90 day bandpass filtered OLR anomalies (FOLR). IS variability explains a large percentage of variance with maximum values over Paraguay, northeastern Argentina, and southern Brazil.

Too Hot to Profit? Climatic Stress and Farm‐Level Performance in Italian Viticulture

Business Strategy and the Environment, Volume 35, Issue 4, Page 5823-5840, May 2026.
ABSTRACT This paper investigates the economic impact of long‐run climatic conditions on Italian wine farms by applying a Ricardian framework to 1431 firms from the 2022 RICA‐FADN survey. We combine farm‐level revenues with viticulture‐specific agroclimatic indicators to assess how climate stress shapes profitability across 77 Italian NUTS3 provinces ...

Intercomparison of the northern hemisphere winter mid-latitude atmospheric variability of the IPCC models

, 2006
We compare, for the overlapping time frame 1962-2000, the estimate of the northern hemisphere (NH) mid-latitude winter atmospheric variability within the XX century simulations of 17 global climate models (GCMs) included in the IPCC-4AR with the NCEP and

Seasonal Variability of Precipitating Systems in Four Radar Domains of Northeast Brazil

International Journal of Climatology, Volume 46, Issue 6, May 2026.
This study analyzes the climatology and evaluates how the physical aspects of precipitating systems are influenced by the dry and wet seasons in Northeast Brazil, highlighting seasonal variations in the frequency, size, intensity, and duration of these systems in the regions of Natal, Maceió, Petrolina, and Salvador.

Sunshine Duration in Brazil From Meteosat (1983–2020): Climatology, Variability and Long‐Term Trends

International Journal of Climatology, Volume 46, Issue 6, May 2026.
Using nearly four decades of Meteosat satellite data (1983–2020), this study presents a country‐wide climatology of sunshine duration (SDU) in Brazil. The results reveal marked regional contrasts, dominant modes of variability, and significant long‐term trends, providing new information on the most relevant meteorological systems that influence SDU and
