The time-latitude cross section of climatological daily variations of Total Ozone Mapping Spectrometer–Aerosol Index (TOMS-AI) (upper panel) and the GEWEX Global Precipitation Climatology Project (GPCP) 5-day mean rainfall (lower panel) over the Indian subcontinent show that the high aerosol region in Northern India during June–July overlaps with the rain area, indicating that aerosols may inte...

The relationship between vegetation and precipitation has been studied extensively, but little is known about its mechanistic linkage to agro-ecosystem sustainability. In this study, we used 250 m MODIS NDVI 16-day composite data and precipitation data for the period 2001–2005 to evaluate the connection between vegetation and precipitation in the Jinghe River watershed of the central Loess Plat...

Japanese encephalitis (JE) is one of the most important mosquito-borne viral diseases in Asia. Pigs are a natural host and the amplifier of JE virus. The sero-conversion rate to JE virus in sentinel pigs reflects the activity of JE virus in the region. We analyzed whether precipitation has any effect on the sero-conversion rate to JE virus in sentinel pigs. Linear regression analysis was perfor...

This study tested multiple hydrologic mechanisms to explain snowpack dynamics in extreme rain-on-snow floods, which occur widely in the temperate and polar regions. We examined 26, 10 day large storm events over the period 1992–2012 in the H.J. Andrews Experimental Forest in western Oregon, using statistical analyses (regression, ANOVA, and wavelet coherence) of hourly snowmelt lysimeter, air a...

Precipitation extremes play a key role in flooding risks over the Huaihe River Basin, which is important to understand their hydrological impacts. Based on observed daily precipitation and streamflow data from 1958 to 2009, eight precipitation indices and three streamflow indices were calculated for the study of hydrological impacts of precipitation extremes. The results indicate that the wet c...

A climatic analysis of temperature and precipitation ®elds in the Sardinia region is developed. The main purpose of this work is the characterization of temperature and precipitation ®elds to better understand Sardinia's climate. Principal component analysis (PCA) and singular spectrum analysis (SSA) have been applied to maximum and minimum temperature and to cumulative daily precipitation data...

The impact of sub-grid variability of precipitation and canopy water storage is investigated over Central-South Europe by applying a new canopy interception scheme into the Community Atmosphere Model (CAM, Version 3) coupled with the Community Land Model (CLM, Version 3). The study shows that while sub-grid variability exerts great impact on the land surface water budget, the impact on the atmo...

Climatic variability can lead to large-scale alterations in the hydrologic cycle, some of which can be characterized in terms of indices involving precipitation depth, duration and frequency. This study evaluated the spatiotemporal behavior of precipitation indices over the Kentucky River watershed for both the baseline period of 1986–2015 and late-century time frame of 2070–2099. Historical pr...

6 The England and Wales Precipitation (EWP) dataset is a homogeneous time series of 7 daily accumulations from 1931 to 2014, composed from rain gauge observations spanning 8 the region. The daily precipitation statistics are shown to be well described by a Weibull 9 distribution, which is used to define extremes in terms of percentiles. Computed trends in 10 annual and seasonal precipitation ar...
