NAM 2017: Call for abstracts on “The Physical Processes Underlying Space Weather”

We invite abstract submission for the National Astronomy Meeting 2017 session “The Physical Processes Underlying Space Weather: Formation, Eruption and Propagation of Coronal Mass Ejections”.  


The aim of the session is to bring together solar and heliospheric physicists, both modelers and observers, to discuss the formation and evolution of magnetic flux ropes with particular focus on:

  1. what are the universal physical mechanisms responsible for triggering solar eruptions,
  2. how and when magnetic flux ropes are formed,
  3. how their structure evolves during their propagation through the inner heliosphere,
  4. how the structure of the interplanetary magnetic clouds relate to their source regions on the Sun.

 

The NAM 2017 will be hosted at the University of Hull (UK) during the 2nd-6th July 2017. We note that this is shortly before the IAU Symposium on Space Weather of the Heliosphere in Exeter (UK), and that this perhaps provides an opportunity for colleagues from further afield to combine two meetings.

Please note that the deadline for abstract submission is April 14, 2017.

For more information, please visit the conference website: https://nam2017.org/

Identification of the different magnetic field contributions during a geomagnetic storm

fig_angeo_da_pdf

 

We announce to the community a recently published paper on the identification of the different magnetic field contributions during a geomagnetic storm in magnetospheric and ground observations. The authors of the paper are SWICo members  from different institutions.

Abstract:

We investigate the time variation of the magnetospheric and Earth’s magnetic field during both quiet and disturbed periods. We identify the timescale variations associated with different magnetospheric current systems, solar-wind–magnetosphere high-frequency interactions, ionospheric processes, and internal dynamics of the magnetosphere. In addition, we propose a new local index for the identification of the intensity of a geomagnetic storm on the ground.

Spatial interactions in a modified Daisyworld model

We point out to the community an interesting paper by the UNICAL group on a modified version of the Daisyworld model. First author of the paper is the SWICo member Tommaso Alberti.

daisyworldAbstract:

We investigate a modified version of the Daisyworld model, originally introduced by Lovelock and Watson to describe in a simple way the interactions between an Earth-like planet, its biosphere, and the incoming solar radiation, where spatial dependency, variable heat diffusivity, and greenhouse effect are explicitly taken into account.
In this way, we obtain a more realistic energy-balance model to investigate the evolution of the Earth’s climate by considering several influencing factors.

The model is based on a hypothetical planet, like the Earth, which receives the radiant energy coming from a Sun-like star, and is populated by two kinds of identical plants differing in their color: white daisies reflecting light and black daisies absorbing light. The interactions and feedbacks between the collective biota of the planet and the incoming
radiation form a self-regulating system where the conditions for life are maintained.

We show that the diffusion process is able to destabilize the system and plays an important role in setting the symmetry with respect to the equator. The greenhouse effect, modeled through a grayness function, affects the temperature evolution and contributes to self-regulating the planet climate, in agreement with observational data analysis.

The equilibrium state is significantly dependent on the initial conditions. The initial conditions of daisy
coverage influence the vegetation profiles although they do not significantly modify the temperature behavior. This implies that a different surface coverage by oceans, ice and vegetation can locally change their interactions, producing local micro-climate (similar to the climatic zones).
This model could be very useful in the framework of climate changes, due to its simplicity, to provide both global and local informations about temperature and biosphere changes.

Registration is open for the 7th Solar Orbiter workshop

solar_orbiter_payload_annotatedWe are happy to re-post here the announcement of the 7th Solar Orbiter workshop:

It is a pleasure to announce that the 7th SolO workshop Website is ready for registration and abstract submission. Please convey the news to as many colleagues as possible. A second announcement will appear in the next issues of SolarNews and SPA newsletters.
Deadline for abstract submission is 31 December. We are supposed to notify the authors on whether their contribution are oral or posters by mid January.

Planetary space weather: scientific aspects and future perspectives

We announce to the community a recently published review-paper on planetary space weather. First author of the paper is the SWICo member Christina Plainaki.

Link to the paper

Abstract:

In this paper, we review the scientific aspects of planetary space weather at different regions of our Solar System, performing a comparative planetology analysis that includes a direct reference to the circum-terrestrial case. Through an interdisciplinary analysis of existing results based both on observational data and theoretical models, we review the nature of the interactions between the environment of a Solar System body other than the Earth and the impinging plasma/radiation, and we offer some considerations related to the planning of future space observations. We highlight the importance of such comparative studies for data interpretations in the context of future space missions (e.g. ESA JUICE; ESA/JAXA BEPI COLOMBO). Moreover, we discuss how the study of planetary space weather can provide feedback for better understanding the traditional circum-terrestrial space weather. Finally, a strategy for future global investigations related to this thematic is proposed.

H2020 SWe 2016

Vi segnaliamo i bandi H2020 in apertura il prossimo 8 novembre

Poniamo la vostra attenzione in particolare alle call:

COMPET-4-2017: Scientific data exploitation
COMPET-5-2017: Space Weather

La call “Scientific data exploitation” è stata esplicitamente estesa all’eliofisica ed all’esplorazione del sistema solare, mentre nel 2015 era limitata al sole e alle scienze planetarie.
