Article
Water has always been a driver of human mobility, migration, and displacement. But water is increasingly central to explaining environmental migration in the context of climate change. Most studies of the relationship between water and environmental migration are framed around punctuated, extreme weather events and disasters that either limit agric...
Article
This study examines the annual cycle of monsoon precipitation simulated by models from the Coupled Model Intercomparison Project phase 6 (CMIP6), then uses moist energy diagnostics to explain globally inhomogeneous projected future changes. Rainy season characteristics are quantified using a consistent method across the globe. Model bias is shown t...
Article
Full-text available
As Arctic sea ice declines in response to climate change, a shift from thick multiyear ice to a thinner ice cover is occurring. With this transition, ice thicknesses approach a threshold below which ice no longer insulates the atmosphere from oceanic surface fluxes. While this is well known, there are no estimates of the magnitude of this threshold...
Article
This article presents a review of the scientific literature on detection, sources of variability, and predictability of the timing of monsoons. The timing of monsoons is characterized by the beginning (commonly referred to as onset) and end (commonly referred to as demise, cessation, retreat, or withdrawal) dates of the summer monsoons.The main met...
Article
The Rainy and Dry Seasons (RADS) dataset, a new compilation of precipitation statistics available to the public, is described. The dataset contains the dates of onset and demise of the rainy season (one date per year), the duration of the rainy and dry seasons, and the accumulated precipitation during the rainy and dry seasons. The methodology for...
Chapter
This chapter presents a review of the Heated Condensation Framework (HCF) theory and applications. The HCF offers an alternative approach to methods of parameterizing convection based on parcel theory. Formulated to take into account the role of atmospheric mixing within the boundary layer, the HCF uses profiles of temperature and humidity to quant...
Chapter
Full-text available
This chapter summarizes current efforts to predict on sub-seasonal timescale monsoons features such as the beginning/end dates, duration, accumulated precipitation, and active/break phases. We present analyses related to the spatial coherence of rainfall anomalies at sub-seasonal 7-90 days timescales , retrospective sub-seasonal forecasts of monsoo...
Article
Various land surface treatments in a suite of subseasonal-to-seasonal forecasts are applied to diagnose the degree to which potential predictability from the land surface is harvested, where breakdowns occur in the process chains that link land surface states to atmospheric phenomena, and the role played by memory in the climate system. Version 2 o...
Article
The seasonal predictability of austral summer rainfall is evaluated in a set of retrospective forecasts (hindcasts) performed as part of the Minerva and Metis projects. Both projects use the European Centre for Medium-Range Weather Forecasts (ECMWF) Integrated Forecast System (IFS) coupled to the Nucleus for European Modelling of the Ocean (NEMO)....
Chapter
Full-text available
This chapter summarizes current efforts to predict monsoons features (such as the beginning/end dates, duration, accumulated precipitation, and active/break phases) on sub-seasonal timescales. The spatial scales of rainfall anomaly in various time scales as well as retrospective forecasts of onset and demise of regional-scale monsoon seasons are co...
Chapter
Full-text available
Prediction of regional-scale seasonal amounts of rainfall across the tropical zone is now routinely issued by several research centers, at least since the major warm El Niño Southern Oscillation event of 1997-98. Consisting of at least a 3-month period and grid-points covering several degrees of longitude/latitude, seasonal timescales emphasize the...

Resumo Muitos estudos meteorológicos e climatológicos utilizam metodologias que superestimam ou até subestimam a significância estatística dos resultados. Análises que subestimam o papel de tendências e dependência temporal e espacial nos dados podem levar a conclusões errôneas. Por outro lado, análises desnecessariamente rigorosas podem enfraquece...
Article
Full-text available
It is known that the Amazon region plays an important role in the global energy, hydrological cycle and carbon balance. This region has been suffering from the course of the past 40 years intense land use and land cover changes. With this in mind, this study has examined possible associations between change in spatial and temporal rainfall variabil...
Article
Sub-seasonal to seasonal (S2S) retrospective forecasts from three global coupled models are used to evaluate the predictability of the onset and demise dates of the rainy season over monsoonal regions. The onset and demise dates of the rainy season are defined using only precipitation data. The forecasts of the onset and demise dates of the rainy s...
Article
Full-text available
An updated version of the Heated Condensation Framework (HCF) is implemented as a convective triggering criterion into the National Centers for Environmental Prediction (NCEP) Climate Forecast System version 2 (CFSv2). The new trigger replaces the original criteria in both the deep (Simplified Arakawa-Schubert – SAS) and shallow (SAS based) convect...
Article
Full-text available
A new triggering mechanism for deep convection based on the heated condensation framework (HCF) is implemented into the National Centers for Environmental Prediction climate forecast system version 2 (CFSv2). The new trigger is added as an additional criterion in the simplified Arakawa–Schubert scheme for deep convection. Seasonal forecasts are per...
Article
Full-text available
Retrospective decadal forecasts were undertaken using the Climate Forecast System version 2 (CFSv2) as part of Coupled Model Intercomparison Project 5 (CMIP5). Decadal forecasts were performed separately by the National Center for Environmental Prediction (NCEP) and by the Center for Ocean-Land-Atmosphere Studies (COLA), with the centers using two...
Article
Full-text available
The dominant mode of coupled variability over the South Atlantic Ocean is known as “South Atlantic Dipole” (SAD) and is characterized by a dipole in sea surface temperature (SST) anomalies with centers over the tropical and the extratropical South Atlantic. Previous studies have shown that variations in SST related to SAD modulate large-scale patte...
Article
Full-text available
The South Atlantic Convergence Zone (SACZ) is an intrinsic characteristic of the South American Summer Monsoon. In a recent study, we verified that the main mode of coupled variability over the South Atlantic (South Atlantic Dipole (SAD)) plays a role in modulating the position of extratropical cyclones that affect the SACZ precipitation. In this s...

Full-text available
This study investigates relationships between Atlantic sea surface temperature (SST) and the variability of the characteristics of the South American Monsoon System (SAMS), such as the onset dates and total precipitation over central eastern Brazil. The observed onset and total summer monsoon precipitation are estimated for the period 1979–2007. SS...
Article
This study investigates how the summer thunderstorms developed over the city of São Paulo and if the pollution might affect its development or characteristics during the austral summer (December–January–February–March, DJFM months). A total of 605 days from December 1999 to March 2004 was separated as 241 thunderstorms days (TDs) and 364 non-thunde...

Full-text available
This study examines the variability of the South America monsoon system (SAMS) over tropical South America (SA). The onset, end, and total rainfall during the summer monsoon are investigated using precipitation pentad estimates from the global precipitation climatology project (GPCP) 1979–2006. Likewise, the variability of SAMS characteristics is e...
