Seeking a PhD candidate: Precursors of the anomalous merging
of the Atlantic and
African jets as a way of examining possible predictors to rare dynamical regime changes
Supervised by: Prof. Nili Harnik
(personal web page).
Project description:
This project focuses on understanding and predicting extreme dynamical
events and specifically when the jet stream and storms in the North Atlantic
behave in a very unusual way for a relatively long period. Such a rare state of
the flow occurred for example during winter 2009-10 when the usually separate
Atlantic and African jets merged into one zonal jet, more typical of the
Pacific jet stream, resulting in unusually cold and wet conditions in North
America, Europe and even China (see details here). We propose to apply
a novel rare event algorithm, based on statistical mechanics, to produce an
ensemble of model runs of similar winter flow conditions, to study both the
dynamics of these events, and their predictability using dynamical systems
tools.
The project is part of the “European weather Extremes: DrIvers, Predictability and Impacts” (EDIPI)
project led by a an international consortium of universities, research centres and private companies aiming to further our
holistic understanding of temperature, precipitation (incl. drought) and
surface wind extremes over Europe. As such, you will be part of a
leading cohort of early-career researchers studying different aspects of
climate extremes in Europe, from atmospheric dynamics to public health and
agricultural impacts, and will have access to a rich programme
of training activities and research exchanges. These are designed to enhance your
career prospects in both academia and the private sector. This
project has received funding from the European Union’s Horizon 2020 research
and innovation programme under the Marie Skłodowska-Curie
Fellows in Innovative Training Networks (ITN) program - grant agreement
No. 956396.
Where: Geophysics Department, Porter School of the
Environment and Earth Sciences, Tel Aviv University, Israel
When: Starting 01-09-2021 or as
otherwise agreed.
Duration: A three-year PhD project.
Salary and conditions: The salary conditions will follow the European Marie
Curie ITN rules (see the 2019 allowance amount).
Eligibility: ITN program requires that applicants must not have
resided and not have carried out their main activity (work, studies, etc.) in
Israel for more than 12 months in the 3 years immediately before the
recruitment date. The applicant must be in the first 4 years (full-time
equivalent research experience) of his/her research careers and must not have
been awarded a doctoral degree.
Further requirements by Tel Aviv University can be found here: https://en-go.tau.ac.il/phd, or by emailing the TAU
Geophysics PhD program coordinator Yafa Cohen-Hadari: yaffac@tauex.tau.ac.il
Further requirements: Candidates should have a background in either climate sciences, atmosphere dynamics, geophysical fluid dynamics, or physics. Experience running atmospheric general circulation models is an advantage. The candidate should be able to demonstrate motivation and a strong
eagerness to learn and have the ability to work both independently and as part
of a team.
Duties: Besides the PhD related course and research work, the fellow must be
willing to travel and will be required to complete international secondments.
Specifically, major parts of the project will be carried out in collaboration
with Prof. Freddy Bouchet at ENS de Lyon, France
Applications must include a cover letter, a CV, any document
that might attest the academic results during the last two years, 2
recommendations letters. These should be sent directly to harnik@tauex.tau.ac.il
The closing date is 31st May, 2021. After 31st
May 2021, please contact harnik@tauex.tau.ac.il to
know if the position has already been granted or not.
