AROME-WMED,a real-time mesoscale model designed for the HyMeX special observation periods
AROME-WMED real-time mesoscale model designed HyMeX special observation periods
2015/8/6
During autumn 2012 and winter 2013, two special observation periods (SOPs) of the HYdrological cycle in the Mediterranean EXperiment (HyMeX) took place. For the preparatory studies and to support the ...
An observation-constrained multi-physics WRF ensemble for simulating European mega heat waves
multi-physics WRF ensemble simulating European mega heat waves
2015/8/6
Many climate models have difficulties in properly reproducing climate extremes, such as heat wave conditions. Here we use the Weather Research and Forecasting (WRF) regional climate model with a large...
GEWEX Cloud System Study (GCSS) cirrus cloud working group: development of an observation-based case study for model evaluation
GEWEX Cloud System Study cirrus cloud working group observation-based case study model evaluation
2014/12/10
The GCSS working group on cirrus focuses on an inter-comparison of model simulations ranging from very detailed microphysical and dynamical models through to general circulation models (GCMs). The pas...
How Does Hydropeaking Alter the Hydrology of a River Reach? A Combined Water Budget, Modeling, and Field Observation Study. Deerfild River, Massachusett
Alter the Hydrologic of a River Reach A Combined Water Budget Modeling Field Observation Deerfield River Massachusetts
2014/10/21
Hydroelectric releases on the Deerfield River in northwestern Massachusetts affect surface water-groundwater interactions there by daily reversing the head gradient between river and groundwater. Arti...
The effect of observation timescales on the characterisation of extreme Mediterranean precipitation
The effect of observation timescales characterisation extreme Mediterranean precipitation
2010/9/10
This paper analyses the behaviour of five rainfall indicators (maximum intensity, cumulative rainfall, irregularity, probability of rain and persistence of rain) over different observation timescales...

Rainfall observation X-band space-borne Synthetic aperture radar
2009/12/16
Satellites carrying X-band Synthetic Aperture Radars (SAR) have recently been launched by several countries. These provide new opportunities to measure precipitation with higher spatial resolution tha...
Preseismic ULF electromagnetic effect from observation at Kamchatka
Preseismic ULF electromagnetic effect observation Kamchatka
2009/12/11
Some results of ULF magnetic field observation at Karimshino site (Kamchatka, Russia) since June 2000 to September 2001 are presented here. Using case study we have found an effect of suppression of U...
Observation of surface features on an active landslide, and implications for understanding its history of movement
surface features an active landslide history of movement
2009/12/10
Surface features are produced as a result of internal deformation of active landslides, and are continuously created and destroyed by the movement. Observation of their presence and distribution, and ...
