How will Geospace Respond to a Changing Climate?

Introduction

Scientific issues

Task Group 2 will focus on answering these three key questions over the next 4 years:

1. How do changes in tropospheric wave generation and their propagation through a changing atmosphere affect the dynamics of the MLT?

2. By how much is the anthropogenic effect on the ionosphere/thermosphere enhanced during a quiet sun period?

3. Are PMC/NLC characteristics trending?

To answer these questions, five projects are established characterize and understand the impacts of:

Changes in wave sources

[[Project 1.1 Changes in wave sources (storm tracks, mountain waves, convection and stratospheric heating rates).]]

  • Project leaders:
  • Project members:

Changes in filtering

  • Project leaders:
  • Project members:

Changes in MLTI dynamics and composition

[[Project 1.3 Changes in MLTI dynamics and composition.]]

  • Project leaders:
  • Project members:

Project 2 The enhancement of the anthropogenic effect on the ionosphere/thermosphere during a quiet sun period.

Existing work and plans

The 6th IAGA/ICMA/CAWSES workshop on “Long-Term Changes and Trends in the Atmosphere” (http://www.hao.ucar.edu/TREND2010/index.php) will be held at National Center for Atmospheric Research (NCAR) Center Green Conference Center, Boulder, Colorado, USA, June15-18, 2010, the week before the 2010 CEDAR (Coupling, Energetics, and Dynamics of Atmospheric Regions) workshop, which will also be held in Boulder.
