Spatiotemporal changes and modulations of extreme climatic indices in monsoon-dominated climate region linkage with large-scale atmospheric oscillation

Atmospheric Research, 2021
Abstract Spatiotemporal changes in six precipitation and five temperature extreme indices of Bangladesh and their linkage with nine ocean-atmospheric oscillation indices have been evaluated in this study to provide necessary information for adaptation planning and development of early warning systems.

Seasonal prediction of monthly precipitation in china using large-scale climate indices

Advances in Atmospheric Sciences, 2009
In this study, seasonal predictions were applied to precipitation in China on a monthly basis based on a multivariate linear regression with an adaptive choice of predictors drawn from regularly updated climate indices with a two to twelve month lead time. A leave-one-out cross validation was applied to obtain hindcast skill at a 1% significance level.

Variability, teleconnection, and predictability of Korean precipitation in relation to large scale climate indices

Journal of Hydrology, 2019
Abstract Spatiotemporal variability, teleconnection, and predictability of the Korean precipitation related to large scale climate indices were examined based on leading patterns of observed monthly Rx5day and total precipitation through an empirical orthogonal teleconnection (EOT).

Northern hemispheric NDVI variations associated with large-scale climate indices in spring

International Journal of Remote Sensing, 2003
Large-scale atmospheric systems, such as the Southern Oscillation, North Atlantic Oscillation, and so on, are important climatic change indicators over the northern hemisphere. These systems play essential roles in regional-to-continental scale climate fluctuation and vegetation activity in response to global change.

Spatio‐temporal variations of wet and dry spells in Iran and their association with large‐scale climatic indices

International Journal of Climatology, 2023
AbstractThe spatial and temporal variations of wet and dry spells may be related to large‐scale climatic indices. To date, no comprehensive study has been conducted on Iran's spatial and temporal variations of wet and dry spells. To fill this gap, 14 wet/dry spell indices were calculated for 512 rain gauges across Iran from 1985 to 2016.

Teleconnection between low flows and large-scale climate indices in Texas River basins

Stochastic Environmental Research and Risk Assessment, 2017
Understanding low flow variability is critical for assessing water quality and health of riverine ecosystems in a river basin. Low flows are dependent on human water abstraction as well as the climate variability. This paper investigates the changing nature of low flows and their association with large-scale climate variability for different watersheds

Modification of input datasets for the Ensemble Streamflow Prediction based on large-scale climatic indices and weather generator

Journal of Hydrology, 2015
Summary Ensemble Streamflow Prediction (ESP) provides an efficient tool for seasonal hydrological forecasts. In this study, we propose a new modification of input data series for the ESP system used for the runoff volume prediction with a lead of one month.

Multiscale characteristics of Jing-Jin-Ji’s seasonal precipitation and their teleconnection with large-scale climate indices

Theoretical and Applied Climatology, 2018
Using wavelet theory, Mann-Kendall non-parametric test, principal component analysis, and correlation analysis, the study investigated the change characteristics and periodic variation of seasonal precipitation and their relationships with seven large-scale global climate indices including Nino 3.4, Southern Oscillation Index (SOI), Pacific Decadal ...

Surface Climate and Streamflow Variability in the Western United States and Their Relationship to Large‐Scale Circulation Indices

Water Resources Research, 1991
A statistical analysis was undertaken to determine the nature and magnitude of the relationship of precipitation, temperature and streamflow in the western United States to large‐scale atmospheric circulation patterns. The Southern Oscillation Index (SOI) was used as an indicator of the El Niño/Southern Oscillation (ENSO) and the PNA index as an ...

Modelling phytoclimatic versatility as a large scale indicator of adaptive capacity to climate change in forest ecosystems

Ecological Modelling, 2011
Abstract CLIMPAIR is a new phytoclimatic model, correlative and niche-based, which simultaneously assesses non-linear, non-statistical and dual measurements of proximity/potentiality of a site with respect to a number of climatic ranges of species, defined by convex hulls, within a suitability space.
