Extreme rainfall regime characterization in Sardinia using daily rainfall data
… is fundamental the knowledge of the ``extreme rainfall regime'' in the area where the hydraulic structures must be set up. Indeed the design flood is commonly evaluated as output of rainfall-runoff models that receive as input the quantitative description of a rainfall extreme event with a …

Comparing A Simple Stochastic Weather Generator With Two Common Statistical Techniques For Gap-filling Daily Rainfall In Hawaiʻi
… varying lengths are present in many historical daily rainfall records for Hawaiʻi. Countless gap-filling techniques exist, some more complex than others, and all are challenged by the spatially variable, complex terrain in Hawaiʻi. A stochastic weather generator (SWG) attempts to model the …

Statistical Analysis of Seasonal Precipitation for the Lake Pontchartrain Basin and Associated Watersheds
… analysis was performed on a dataset of daily rainfall observed at 63 south Louisiana stations from 1836 to 2002. Each station record was examined for data quality and continuity with special attention to time periods surrounding station relocation or equipment exchange. Mean Areal …

The relationship between temperature, rainfall, and tree swallow fledging times
… temperature, average temperature, maximum rainfall experienced in one day during a fledging period, and average daily rainfall on how long it takes tree swallow nestlings in Tennessee to fledge using multi-linear regression and linear mixed-effects modeling. I found that minimum …

Assessment of Future Impact of Climate Change on Structural Protections and Hydrological Extremes – Floods
… region. The modelling framework prioritizes rainfall as the primary driver of flood flow generation and enables the assessment of various climate change scenarios produced by Global Circulation Models (GCMs). The study created a statistical downscaling model called SDCRR, using the Volterra …

Topics in interpolation and smoothing of spatial data
… one being to extend the availability of a daily rainfall model for southern Africa to sites at which little or no rainfall data is available, using data from nearby sites, and the other arising from a need to improve the species abundance estimates used to produce maps for the Southern …

The development of Intensity Duration Frequency curves under climate change considerations using Remote Sensed rainfall data in Uganda
The intensification of extreme rainfall poses significant risks to hydrological infrastructure, particularly in data-scarce regions such as Uganda. Reliable intensity–duration–frequency (IDF) curves are essential for climate-resilient design, yet their development is constrained by the lack of …

CHANGES IN FIRE SEASON PRECIPITATION IN IDAHO AND MONTANA FROM 1982-2006
… precipitation trends were investigated using daily rainfall data obtained from seventy-six Remote Automated Weather Stations (RAWS) across Idaho and Montana for the period 1982 to 2006. Missing and erroneous values from each station were corrected with gridded data from the North American …

A climatological study of the Keetch/Byram Drought Index and fire activity in the Hawaiian Islands
… and flammability of vegetation. Incorporating daily maximum temperatures and daily rainfall amounts, the Keetch and Byram Drought Index (KBDI) estimates the amount of soil moisture by tracking daily maximum temperatures and rainfall. For the first time, the climatological relationship between …

The analysis of tropical temperate trough-associated rainfall onsets and their influence on maize yields in the Maize Triangle, South Africa
… troughs (TTTs) that were associated with rainfall onsets in the Maize Triangle, South Africa, were analysed during the period from 1979 to 2018. Maize yields for agricultural regions within the Maize Triangle were also investigated to determine if the association of the above-mentioned …

Forecasting of rainfall using statistical downscaling model (SDSM) – general circulation model (GCM) for future estimation of rainwater harvesting
Changes in the spatial and temporal rainfall pattern affected by the climate change need to be investigated as its significant characteristics are often used for managing water resources. In this study, the impacts of climate change on rainfall variability in Johor was investigated by using General …

Capability of CORDEX RCMs in simulating extreme rainfall events over South africa
In South Africa, extreme rainfall events often lead to widespread destruction, damage infrastructure, displace communities, strain water management and even destroy lives. Past studies have shown that reliable predictions of extreme rainfall events from regional climate models (RCMs) could help …

Extreme rainfall events over the Pongola-Mtamvuna Water Management Area of South Africa
… southern Africa experiences substantial rainfall variability both spatially and temporally, due to regional orography, geographic position, and local sea-surface temperatures. Extreme weather conditions such as droughts and floods are not uncommon and can result in both positive and …

Water use of Pinus radiata D. Don on bare ground at the Lincoln agroforestry experiment, Canterbury, New Zealand
This study evaluated the rainfall distribution and the soil water storage at different positions of Clone 3 and Seedling trees of Pinus radiata genotypes grown in bare ground during early summer (September 14 to 30 November) 1994. The predawn and mid-day plant water potential of two genotypes was …

An assessment of the onset of summer rainy season in Southern Africa - case study of Botswana
… onset, reliability and performance of seasonal rainfall. Failure of seasonal rains may signal food deficits or worse. Farmers, water conservationists and government bodies responsible for food security, all have an interest in seasonal rainfall: onset, approximate dates for start of the season …

An investigation of the impacts of intra-seasonal rainfall variability on the maize growing season in Limpopo Province, South Africa from 1990-2014
… food security and improving livelihoods. Rainfall consistency and intensity is an essential requirement for successful maize growing seasons. The variability of intra-seasonal rainfall characteristics such as onset, cessation and wet and dry spells threatens maize yields in Southern …

Monsoon surges, tropical cyclones and extreme rainfall events in NW Madagascar
Rainfall variability in NW Madagascar and the kinematics and thermodynamics of flood-producing weather systems affecting the region are examined. Daily rainfall in the austral summer are used to select 16 cases for the composite analysis of flood events in the period 1987-1992. In addition two …
