Regional climate model evaluations of long-term changes in total precipitation and high precipitation events
Extreme events, including precipitation extremes, can have severe impacts on human society and on ecosystems. In the late 20th century, heavy precipitation events tend to occur with increasing frequency or intensity proportion to total rainfall over most land areas in the world. Precipitation, …

Relationship Between West African monsoon precipitation characteristics and maize yields across Sub-Saharan West Africa
… region where crops are near exclusively rainfed, precipitation from the West African Monsoon (WAM) plays a significant role in the region's food production. This study aims to add to the limited literature on the relationship between country-level maize yields and the WAM, particularly through the …

Precipitation Recycling as a Mechanism for Ecoclimatological Stability Through Local and Non-Local Interactions
Different physical mechanisms drive precipitation recycling in each region. In the Midwestern United States, evapotranspiration is not significantly affected by soil moisture anomalies, and there is a high recycling ratio during periods of reduced total precipitation. The reason is that, during …

Food Supply Early in the Plant Growing Season: Influences from Elk Abundance and Precipitation
… a 15-year period when population abundance and total precipitation varied. The food supply was a 50-hectare meadow complex that was divided into 7 sectors, 2-10 hectares in size. I compared linear mixed effect models using Aikaike Information Criterion to determine whether elk abundance and …

Representation of Mean Precipitation and Decadal Variability in Atmosphere Models
… sea surface temperature variability affects precipitation over Europe and the Sahel using the atmosphere model OpenIFS. I found that European extreme precipitation is better represented at higher horizontal resolution, while the model time step has a limited effect on total precipitation …

Variation and Change in Daily Precipitation Extremes Across the United States Since the Mid-20th Century
… in the spatial and temporal characteristics of precipitation. Although precipitation is inherently variable through time and space, for some water-sensitive stakeholders, the evenness with which precipitation is distributed through a time interval rivals the importance of total precipitation …

Dynamic and Thermodynamic Controls on the Amount and Distribution of Orographic Precipitation
… controlling the amount and distribution of precipitation in mountainous terrain. In Chapter 2, linear theory and numerical simulations are used to investigate how the tropopause affects the vertical structure of mountain waves, and in turn orographic precipitation. In idealized numerical …

Measuring and modeling suspended sediment and nutrient yields in a mixed-land use watershed of the central United States
… of the central USA. Highly variable annual precipitation was observed during the four year study period (2010-2013) with the greatest suspended sediment and nutrient yields during 2010 (record setting wet year) and least yields during 2012 (extreme drought year). Estimated annual suspended …

An East Coast Winter Storm Precipitation Climatology
… compiled climatology of ECWS events, an ECWS precipitation climatology is developed for the eastern United States from 1951-1952 to 2005-2006, using an automated procedure. This climatology consists of the percentage of snowfall and precipitation from ECWS, on average per snow year. The …

Potential impact of stratospheric aerosol geoengineering on projected temperature and precipitation extremes in South Africa
… frequency and magnitude of temperature and precipitation extremes due to anthropogenic warming. The aim of this study is to investigate how SAI deployment would influence temperature and precipitation extremes over South Africa's climatic zones in the future (2075–2095). Climate model …

Examination of Abiotic Drivers and Their Influence on Spartina alterniflora Biomass over a Twenty-eight Year Period Using Landsat 5 TM Satellite Imagery of the Central Georgia Coast
… a suite of abiotic drivers. River discharge, total precipitation, minimum temperature, and mean sea level had positive relationships with and best explained biomass for all dates. Additional results, using seasonally binned data, indicated biomass was responsive to changing combinations of …

Multi-Satellite Remote Sensing of Land-Atmosphere Interactions: Advanced Data-Driven Methodologies for Passive Microwave Retrievals of Flood and Precipitation
… the soil saturated zones, and (2) the precipitation phase (rainfall or snowfall). Remote sensing of snowfall is still very new and challenging despite that snowfall accounts for the majority of total precipitation events over mid- to high latitudes and its spatial distribution …

Toward assessing the effects of aerosols on deep convection: a numerical study using the WRF-Chemistry model
… important role in the development of clouds and precipitation. Few meteorological models have been developed or adapted to simulate aerosols and their contribution to cloud and precipitation processes. The Weather Research and Forecasting model (WRF) has recently been coupled with an atmospheric …
