Climate Influences Wildfire Activity Through Opportunity: An Event-Scale Perspective

Fire
Annual area burned correlates with temperature and fuel aridity, yet extreme wildfire outcomes arise from a small fraction of fires and rapid-growth days.

How Well Do CMIP6 Models Simulate the Influence of the West African Westerly Jet on Sahel Precipitation?

International Journal of Climatology, EarlyView.
Climate models generally reproduce the WAWJ and August peak but simulate its onset prematurely and too strongly relative to ERA5. CMIP6 simulations struggle to reproduce the jet–precipitation relationship in the Sahel and underrepresent associated moisture transports.

Rainfall intensity estimation at night using deep learning and urban surveillance cameras in Jiangsu Province, China

Journal of Hydrology: Regional Studies
Study region: This study was conducted in the Yangtze River Delta of eastern China, focusing on the highly urbanized corridor of Nanjing, Yangzhou, and Wuxi (Jiangsu Province), where the nighttime surveillance videos were collected during 2022–2025 ...

Impact of Indo-Pacific warm pool Hadley circulation on the seasonal forecast performance for summer precipitation over the western North Pacific

Environmental Research Letters, 2020
The western North Pacific summer climate affects the densely populated East Asian countries, while seasonal forecasting over these regions remains challenging for dynamical models.

Spatiotemporal Evolution of Hydroclimatic Variables in the Brazilian Semi‐Arid Region Through the Aridity Index and Susceptibility to Desertification

International Journal of Climatology, EarlyView.
Over the past 60 years, noticeable changes have been observed in the main hydroclimatological variables, driven by both natural and anthropogenic factors. In the context of climate change, such behaviour may adversely affect the state's economic activities, as well as increase the recurrence of extreme events in the region.

Characterisation of Drought and Wet Events in the Paraíba do Sul River Basin—Brazil

International Journal of Climatology, EarlyView.
Trend analysis identified statistically significant reductions in precipitation (at the 5% significance level) at specific pluviometric stations in São Paulo and Rio de Janeiro, while other areas, mainly in Minas Gerais, experienced significant increases in annual and seasonal rainfall, particularly during summer and spring. These significant trends at

Toward the Standardization of Mesoscale Meteorological Networks

Journal of Atmospheric and Oceanic Technology, 2020
AbstractAlthough they share many common qualities in design and operation, mesonetworks across the United States were established independently and organically over the last several decades. In numerous instances, the unique ways each network matured and developed new protocols has led to important lessons learned. These experiences have been shared in

Analysis of the effect of the coastal discontinuity on near-surface flow [PDF]

Annales Geophysicae, 1998
Conditional sampling is used herein to examine the effect of fetch, stability, and surface roughness changes on wind speeds in the coastal zone. Using data from an offshore wind farm it is shown that at a distance of 1.2–1.7 km from the coast, up to a

Scaling of Short‐Duration, Summer Rainfall Event Temporal Profiles With Warming Over Great Britain

International Journal of Climatology, EarlyView.
Temperature scaling has been used to analyse the temporal profiles of short‐duration, summer rainfall events in Great Britain, for sub‐hourly observed and convection‐permitting climate model (CPM) data. Results show an increase with dewpoint temperature of event total rainfall depth, maximum intensity, concentration and front‐loading.

Data management and analysis with WRF and SFIRE

, 2012
We introduce several useful utilities in development for the creation and analysis of real wildland fire simulations using WRF and SFIRE. These utilities exist as standalone programs and scripts as well as extensions to other well known software.
