14th International Precipitation Conference

Dear Colleagues,

We are happy to announce the 14th International Precipitation Conference (IPC14) which will take place on June 5-9, 2023 at the National Weather Center at the University of Oklahoma in Norman, Oklahoma. The theme of IPC14 is “Emerging directions in precipitation science and applications: going beyond” with emphasis on three main topics: (1) Multi-source observations and modeling of precipitation; (2) Water cycle dynamics from regional to global scales; and (3) Precipitation extremes and hydrological hazards including floods, droughts, and landslides. More information can be found on the IPC14 website.

The goal of this conference is to create a discussion platform for all scientists to define challenges and opportunities, and craft directions for future research in precipitation. The IPC14 organizing committee put together a survey to identify the most critical questions to address during the conference. We would love to hear your thoughts and feedback to improve your experience. The conference agenda and discussions will be designed accordingly to maximize the benefit of IPC14. Please fill out the survey by April 7 to indicate your interest in participating and identify the most critical topics to discuss during the conference.

Please contact the IPC14 Organizing Committee at ipc14@arrc.ou.edu with any questions. Reminders will be sent out periodically.

We look forward to seeing you in Norman on June 5-9, 2023.

Best regards,

Pierre Kirstetter

on behalf of the IPC14 organizing committee

Workshop ‘Clouds containing Ice Particles’ – 23. – 26 July, 2023

Workshop ‘Clouds containing Ice Particles’
                   23. – 26 July, 2023

Where: Johannes-Gutenberg University Mainz, Mainz, Germany
https://www.uni-mainz.de/, https://www.mainz.de/en/index.php

When: 23 – 26 July, 2023
(the week after the IUGG 2023 in Berlin)

What:
The intention of the workshop is to discuss all aspects of cirrus and mixed-phased clouds – the least understood cloud types, but contributing significantly to the uncertainty in climate predictions.

The topics of the workshop are intended to be comprehensive, from in-situ and remote sensing observations of clouds to their modeling on all scales. We encourage contributions on the state of knowledge, new findings and open questions, as well as on experimental, theoretical and computational methods used in research.

The workshop will be open for ∼75 guests, registration fees will be around 50 Euro,
Sunday: ice breaker,  Mon-Wed: coffee + cookies and  lunch snack  will be provided.

More information on the registration deadline, abstract submission and further
                   organizational issues will be send around soon.
                                    For the moment,
                       please save the date (23 – 26 July 2023)
                                     and let us know
                         (mail to: m.kraemer@fz-juelich.de)
                                  if you plan to attend
                             until 30 November 2022
            so that we can plan accommodation and catering.

ICCP Journal Club Schedule

The ICCP Journal Club is continuing with monthly presentations on the last Wednesday of the month at 15 UTC.

The link to register for the event is https://iamas.us5.list-manage.com/track/click?u=0fbe4492c6a887b504afdf7ca&id=4d15eecec0&e=364b76fa38.

This link allows you to register for the event. Upon registering, you will be sent the zoom meeting link. Note that this link is the same for all weeks. Due to switches during daylight savings time, please check the time conversion for your time zone–the zoom link for the meeting may not show the correct time. The meetings are at 15 UTC.

Note that we are also requesting volunteers for speakers at future meetings in fall 2023.  Please let us know if you would like to make a presentation.

A complete updated list of all the planned sessions for the journal club is included below.

Kind regards,

Martina Krämer, Greg McFarquhar and Odran Sourdeval

Abstract
Almost all cloud droplets and many ice crystals form on small (nanometre to micron sized) particles known as aerosols. Increases in aerosols from human activity have increased the concentration of droplets in clouds since the industrial revolution, making clouds more reflective and cooling the climate offsetting a significant fraction of the warming from greenhouse gases. Unfortunately, clouds are highly variable which makes the impact of aerosols difficult to isolate. This means that the impact of aerosols on clouds remains one the most uncertain anthropogenic forcing of the climate system.

Here we provide a way around this problem, by using isolated sources of aerosol as natural experiments into cloud behaviour. By matching satellite observations of clouds to new datasets on ship positions and emissions, we can characterise the aerosol-cloud system in hundreds of thousands of cases. This allows us to measure not only which clouds are sensitive to aerosols, but how sensitive they are and how quickly they respond to changes in their environment. As well as providing new insights into cloud processes useful for constraining models, it also demonstrates a way to monitor shipping pollution in the open ocean.

 
Dr. Edward Gryspeerdt is a Royal Society University Research Fellow in the Department of Physics at Imperial College London. He previously worked at the Universities of Leipzig and and Oxford, looking at aerosol-cloud interactions and cloud physics in observations and models.
