US Air Force Operational Weather Structure and The Meteorological Forecast Process
November 28, 2018 11:00 am
CIRA Directors Conference Room
Presented by: Kerrin Caldwell, Major, USAF
Hosted by:
Chief, Air Force Weather Program Requirements & Resources
The operational design and strategic construct of weather operations within the Air Force weather architecture is rapidly changing. The motto of “bring the future faster” has allowed for the introduction of unconventional training methods and forecasting techniques being utilized by today’s weather operators. New capability requirements upgrades to our weather data assimilation center has restructured the way Air Force weather operations utilizes numerical weather modeling and forecasting.
Introduction on South Korean Meteorological Satellite Programs focusing on Geo- KOMPSAT -2A (GK- 2A) applications
November 13, 2018 11:00 am
CIRA Directors Conference Room
Presented by: Chu-Yong Chung and Eunha Sohn
Hosted by:
Korea Meteorological Administration (KMA)/National Meteorological Satellite Center (NMSC)
Since 2010, KMA has operated and utilized the Communication, Ocean and Meteorological satellite (COMS), which is expected to be available by 2020. KMA is now preparing for a new era of the Geostationary Korea operational multi-purpose satellite (GeoKompsat-2A or GK-2A; launch scheduled in December 2018). GK-2A has a 16-channel Advanced Meteorological Imager (AMI), which is a similar sensor to Himawari-8/9 AHI and GOES-16/17 ABI. We will present the status of… Read more »
Wildfire-Driven Thunderstorms Cause a Volcano-Like Stratospheric Injection of Smoke
October 23, 2018 11:00 am
CIRA Directors Conference Room
Presented by: David A. Peterson
Hosted by: James R. Campbell, Edward J. Hyer, Michael D. Fromm, George P. Kablick, Joshua H. Cossuth, Matthew T. DeLand
Naval Research Laboratory
Intense heating by wildfires can generate a deep, smoke-infused thunderstorm, known as pyrocumulonimbus (pyroCb). This extreme weather phenomenon can release a large quantity of smoke particles into the upper troposphere and lower stratosphere. The meteorology driving pyroCb occurrence, combined with increasingly active fire seasons, indicates that pyroCb are a significant and endemic summertime feature in several temperate regions worldwide. A single fire season in western North America can include more… Read more »
A numerical framework for operational coupled fire-atmosphere-fuel moisture-smoke forecasting
October 25, 2018 11:00 am
CIRA Directors Conference Room
Presented by: CIRA
Hosted by: Jan Mandel, University of Colorado Denver (presenting) Adam Kochanski, University of Utah Sher Schranz, CIRA Martin Vejmelka, AVAST
We present an integrated wildland fire model WRF-SFIRE, based on combining a high resolution, multi-scale weather forecasting model WRF, with a semi-empirical fire spread model, a prognostic dead fuel moisture model, and smoke dispersion. Fire-released heat and moisture impact local meteorology. The fuel moisture model is driven by the atmospheric component of the system in order to render the diurnal and spatial fuel moisture variability. The dead fuel moisture is… Read more »
How much will Earth warm? Looking for clues in Earth’s historical energy budget.
October 30, 2018 10:00 am
CIRA Directors Conference Room
Presented by: Mark Richardson
Hosted by:
JPL/Caltech/UCLA JIFRESSE
Abstract: The amount of global warming we expect is controversial in the media. A common metric for this is Equilibrium Climate Sensitivity (ECS), which is the eventual warming following doubled atmospheric CO2. Recently published estimates include “maybe things won’t be that bad” (1.7 °C) and “we could probably destroy most of civilisation” (5.3 °C), but the “consensus” value has stayed stubbornly near 3 °C for decades. This talk aims to… Read more »
