2016 Year of Extremes again

Climate change continued to impact the weather events of 2016. 

January 21, 2016 Extreme East Coast Blizzard Predicted

NWS and the media picked up on an extreme forecast for explosive development and slow movement up the East coast from 22-24 Jan. 2016.  This was a dead hit on Washington, Baltimore, PHL, NYC and the NJ coast where major coastal flooding occurred.  DC, NYC closed offices and all surface traffic on Friday 22Jan as the blizzard’s heavy snow moved up the coast and high winds evolved as explosive deepening off the Va Md shore occurred.  Models predicted this storm quite well and the public officials reacted appropriately.  The media had continuous coverage of the event.  See PPT images of weather event and media.

April 15-20, 2016

Denver and Front Range snow storm dumps up to 51 inches of heavy wet snow on April 15-20, 2016.  This unusual spring storm dumped snow at the rate of 3 inches per hour at our home from 1700-2100 totaling 14 inches.  It closed DIA and I-70 was frequently closed. However by April 18, 2015 I-70 was flowing and we successfully departed DIA for FRA.

Similar heavy spring snow in Slovenia added 50 cm to Kredarica base of 260 cm, and 10 cm in LJU covering Slovenia on April 27, 2016.  It endangered the SLO wine crop in many regions. Skiing resumed at Vogel with 110 cm base that weekend.

The Hydrometerology Testbed (HMT) conducts research on precipitation and weather conditions that can lead to flooding, and fosters transition of scientific advances and new tools into forecasting operations. HMT's outputs support efforts to balance water resource demands and flood control in a changing climate.

2007-2008 WaterNet Meetings and Lectures


March 24-28, 2008

In late March, Dave Matthews and Will Pozzi met with our WaterNet collaboration team at the CNRFC, Central Valley Operations Office, USBR, and the California Department of Water Resources to discuss progress in developing the WaterNet “Community of Practice” and the CNRFC WaterNet Demonstration Project.Meetings were held with Robert Hartman, Hydrologist in Charge, CNRFC, Art Henkel, Senior Hydrologist, and Alan Haynes, HAS Forecaster regarding progress in the Hydrometeorological Test-bed (HMT) and integration of emerging research into operational river forecasting.We then met with Reclamation water operations manager Paul Fujitani and planner Michael Tansey to discuss current water management decision support tools and needs for improved planning and operations.Maurice Roos, CDWR Chief Hydrologist led a meeting with other CDWR engineers and planners to review their interests and needs for improved water supply analysis and prediction.We discussed their snow survey system and how it is used to improve water resource management in California.



NCAR Colorado Headwater Research Program Kickoff:

March 19, 2008


Dr. Roy Rasmussen’s Research Applications Lab (RAL) TIIMES team hosted a kickoff meeting for the Colorado Headwaters Research Program. Dr. Matthews attended at the request of Dr. Paul Houser, CREW to represent him and ourNASA sponsored WaterNet Project.This planning meeting was designed to develop a scientific framework for better long-term analysis and prediction of climate variability and change impacts on the Colorado headwaters to meet the needs of local, state, and interstate water users in this region. The meeting provided a series of excellent presentations on the goals and objectives of CHRP and related scientific issues and challenges that need to be addressed in order to better understand and predict the complex linkages between atmospheric controls of precipitation, snowpack evolution, runoff, and its impacts on water supplies in this critical headwaters region.The scientists discussed a cutting edge approach to very high resolution (2-4 km grid spacing) Weather Research Forecasting (WRF) modeling dynamically coupled to a sophisticated Land Surface Model – Noah-D, and high resolution surface observations and the need for improved remote sensing and in situ aircraft measurements to understand and validate the physical processes simulated in models. While in the initial planning stage, this CHRP holds much promise for making significant research strides to improve long-term predictions of water supplies in the region.

EGU 2008 Annual Meeting, Vienna

April 14-18, 2008

We presented a paper entitled “Extreme Event Analyses from WaterNet: The NASA Water Cycle Solutions Network” describing several examples of extreme events in Slovenia and SE Europe designed to spark interest of EU scientists and decision-makers to join WaterNet.Our key EU collaborators are the Environmental Agency of the Republic of Slovenia (EARS), the Faculty for Civil and Geodetic Engineering (FGG), University of Ljubljana, and the Austrian Meteorological Agency (ZAMG).The EGU meetings provided an excellent forum to develop contacts and our water cycle WaterNet Community of Practice from over 51 sessions in the Natural Hazards Division with over 1460 abstracts covering all aspects from floods to droughts and earthquakes.Other Divisions included the Atmosphere, Climate, Cryosphere, Non-linear processes, Hydrology, Oceanography and Solar-Terrestrial Sciences.Collaborations with the European Space Agency, Joint Research Center and many university researchers in areas from Snow and Avalanche research to bio-fuels energy production and water quality management, emergency management, and hydrologic and climate modeling will be pursued during the next weeks.The European Science Foundation and COST may provide a means to develop workshops and exchanges among EU scientists having interests in the water cycle and related WaterNet human and automated networking.
