Meetings related to VarSITI in 2018

4th International ANGWIN workshop:
Exploration of High-latitude Upper Atmosphere
Wave Dynamics
April 24÷26 2018, São José dos Campos, Brazil

web-address http://www.inpe.br/angwin/

Workshop focus: Measurements and modeling of gravity wave dynamics and coupling in the Antarctic and Arctic regions.

New observational and modeling studies of atmospheric gravity waves have significantly improved our understanding of their important role for transporting energy and momentum within the middle atmosphere and the coupled thermosphere/ionosphere system. However, gravity wave fluxes and dynamical contributions at polar latitudes are not well understood, primarily due to a paucity of measurements. ANGWIN (Antarctic Gravity Wave Instrument Network) is a scientific program initiated in 2011 that utilizes a network of instrumentation operated at several international research stations around Antarctica with the primary research goal of quantifying and understanding the dominant sources, propagation and impact of such dynamical processes on a continental-wide scale.

The goal of this workshop is to combine together new Antarctic and Arctic observations using optical and radio-wave techniques, and results with modeling studies to gain fresh knowledge and insight of their large-scale effects on the general circulation of the polar-regions lower, middle and upper atmosphere and ionosphere. Dynamical coupling processes associated with the gravity wave "hot spot" over the area between the Antarctic Peninsula and South American continent would also be discussed be focus during the workshop.

We solicit participation of potential scientists in this workshop which will include new ground-based and satellite observations, numerical modeling and theoretical studies of polar gravity wave sources, propagation, instabilities, and their effects on local, regional, and global scales.

The workshop is open to all interested researchers and will provide an excellent forum for post-graduate students.

Proposed topics

1. Multi-scale wave dynamics (gravity waves, tides, and Planetary Waves).
2. Wave coupling to different atmospheric layers (troposphere to ionosphere).
3. Sources of gravity waves at high-latitudes;
   signatures in the neutral and ionized upper atmosphere.
4. Comparative studies of Arctic and Antarctic mesosphere and thermosphere dynamics.
5. Potential space-weather impacts of gravity waves in the thermosphere/ ionosphere
6. Dynamical coupling of waves generated by the South American continent and Antarctica.
7. New observational and analysis techniques, and modeling of gravity waves.
8. Any other new results and aspect related to ANGWIN

Venue

The meeting will be held in INPE's main campus located in São José dos Campos city.

It is the biggest city in Paraíbás Valley and it is located about 90 km away from São Paulo capital. There you will find worldwide known technology industries, in addition to having an enormous environmental preservation area. It also has great hotel options.

São José dos Campos is a city that brings culture, tradition and technology together. In its urban center you will find federal scientific research institutes, technology companies, modern architecture buildings, universities, colleges and skilled labour formation. The city rural area has almost 70% of its territory, and a great portion of it is environmental protection areas.

It is the main Paraíbás Valley Metropolitan Region city and the most important aeronautic and aerospace pole in Latin America.

It is strategically located between São Paulo and Rio de Janeiro and it links these cities through modern highways and by its airport; the city is very close to beaches, mountain region and other touristic destinations inside the Valley. You can get to Ubatuba, Campos do Jordão or Aparecida (where you can find the National basilica, the biggest Marian sanctuary in the world) in about two hours by car.
