Regional differences in the effects of El Nino and La Nina on low flows and floods
The response of monthly 7-day low flow, monthly instantaneous peak flow, and monthly frequency of flood events to El Nino and La Nina episodes is investigated for 18 rivers that represent a diverse range of climatic types throughout New Zealand. A significant positive or negative deviation from the long-term average was observed in over half the possible combinations of river, streamflow index,...
متن کاملAutumn Rainfall Anomalies and Regional Atmospheric Circulation along Establishment of Weak La Nina after Strong El Nino in Iran
To study the Iran precipitation anomaly in September to November of 2016 and its probable connection with ENSO (El Nino-Southern Oscillation). This period with similar cases in the previous 55 years (1964, 1983, and 1995 according to forecasting center of NOAA) was investigated. In all cases, ENSO changed from strong El-Nino to weak La-Nina after a very brief neutral period. In the following, o...
متن کاملMid-late Holocene El Nino variability in the equatorial Pacific from coral microatolls
Oxygen isotope ratios in Porites microatolls from Christmas Island in the central Pacific provide highresolution proxy records of El Niño-Southern Oscillation (ENSO) variability since 3.8 thousand years ago (ka). Compared with modern microatolls, reconstructions from fossil microatolls imply that interannual variations in ENSO sea-surface temperature and precipitation were less intense 3.8–2.8 ...
متن کاملEl nino-southern oscillation displacements of the Western equatorial pacific warm pool.
The western equatorial Pacific warm pool (sea-surface temperatures >29 degrees C) was observed to migrate eastward across the date line during the 1986-1987 El Niño-Southern Oscillation event. Direct velocity measurements made in the upper ocean from 1986 to 1988 indicate that this migration was associated with a prolonged reversal in the South Equatorial Current forced by a large-scale relaxat...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
