Session 6: Short Talks 2

Session 6: 10:30-12:00: Chair Jesse Alexander

Over to you. A series of talks followed by an opportunity to talk to the panel.

Spatio-temporal behaviour of cold spells in the Northern Hemisphere

Weronika Osmolska

Cold spells have been associated with elevated mortality rates resulting from the abrupt temperature declines. Anticipating these events in advance is crucial for adequately preparing vulnerable individuals. The study investigates the spatial and temporal evolution of cold spells to unravel their prevalent pathways, persistence, and distribution. The aim is to identify the contributing factors that give rise to these events, enhancing our understanding of the dynamics involved.

Migration of the locations of tropical cyclone rapid intensification over the North Indian Ocean.

Kasturi Singh

The migration of maximum intensity poleward is triggering a shift in the rapid intensification (RI) locations of tropical cyclones (TC) towards the coast of ocean-rim countries. The study investigates changes in the distribution of locations of RI during the pre-monsoon and post-monsoon seasons in recent warming climate scenarios over the North Indian Ocean (NIO) basin. Over the Bay of Bengal (BOB), the percentage of annual RI TC frequency exhibits a stable or slightly decreasing trend (20%-100%), contrasting with a notable surge (50-100%) over the Arabian Sea (AS) in recent years. The distribution of RI TC location gradient is meridional during the pre-monsoon season and is confined zonally below 15oN during the post-monsoon season over BOB. The corresponding locations over AS are confined between 10oN-15oN and 12oN-18oN latitudinal regions. The relation between a simultaneous rise in SST and RH550 is evident during the pre-monsoon season, while the relation fails during the post-monsoon season over BOB. While sea surface temperature and mid-tropospheric relative humidity play a crucial role in RI, the observed changes in tropospheric vertical wind shear patterns and upper-level divergence alignment in current climate conditions are identified as influential factors shaping the distribution of RI location over BOB and AS.

Automated Environmental Data Ingest

Rory Jenns

At CEDA we manage petabytes of environmental (including atmospheric) data, we need ways to intake, organise, and keep track of what comes in - arrivals.ceda.ac.uk is one such service. With the aims to share some complexities of data management and show how automation can aid processes, this presentation follows a dataset through automated upload, ingest, and cataloging using this and associated services and demonstrates how users can upload (and download) environmental data environmental data using these services.

Cloud Optimised Data Formats and Advice for Data Producers

Daniel Westwood

There are many different emerging formats for storing and accessing data, along with a host of historic archival formats in use all over the world. With the growing need for cloud-accessibility and analysis-ready data, it can be difficult as a data provider to know what formats can be used for supplying data to cloud applications and new cloud-based technologies, and the best practices are not well-known. Kerchunk and Zarr are among the most widely known emerging formats for cloud-accessibility; how to implement these, what requirements there are, and how best to optimise data storage are some of the topics I will cover in this talk.
