While scientists have been using climate models to carry out these types of studies since the early s, Clem said, this will be the first climate model study carried out locally at Rutgers on its own in-house computer i.

Clem not only ported the first two models to this Rutgers cluster, he has also proposed additional cutting-edge ways to research, understand and address his research. The forces accounting for the warming vary by season, and it is often difficult to fully attribute a change in surface temperature to a single mechanism due to large, naturally occurring decadal variability in Antarctic temperatures.

The strengthened westerly winds responsible for the warming were largely due to a period of unusually high depletion of the ozone layer above Antarctica during the s and s linked to the anthropogenic release of chlorofluorocarbons refrigerants.

The release of these chemicals, which are now known to deplete ozone, has been banned since the late s following the Montreal Protocol, and over the past decade the Antarctic ozone hole has shown signs of recovery. Since the early s, we have also seen a decrease in warming and surface melting on the eastern Peninsula, though it is unclear exactly why this is. This has largely been caused by a reduction in sea ice and an increase in warm air advection due to an increase in cyclone activity over the high latitudes of the South Pacific.

The increased storminess has been linked to warming ocean temperatures in the central and western tropical Pacific. Explaining the close atmospheric connection between the tropics and Antarctica, Clem explained that organized thunderstorm activity in the tropics is associated with strong vertically rising air that can persist for days and even weeks.

These thunderstorms are often observed to be stronger and more persistent than normal over regions of anomalously warm ocean temperatures, and they tend to follow the warm waters associated with El Nino and La Nina.

As this rising air reaches the top of the troposphere, it spreads poleward toward Antarctica causing a ripple, or Rossby wave, in the upper atmosphere.

With the atmosphere acting like a fluid, Clem said, these atmospheric waves then propagate poleward toward Antarctica, often becoming more pronounced at higher latitudes as the depth of the troposphere becomes shallower, where they can change the location and intensity of weather patterns and affect regional sea ice and thermal advection.

Anomalous warm ocean temperatures in the tropics can persist for months, seasons, and sometimes on-average for decades, leading to persistent impacts that can cause large changes in Antarctic surface climate on decadal time scales. One potential reason that warrants further investigation is that models are inaccurately simulating the relative magnitudes of temperature change from increasing greenhouse gases versus more localized changes in thermal advection and sea ice tied to the regional circulation.

In other words, there are competing forces influencing temperature change in Antarctica: ubiquitous warming of the continent due to increasing greenhouse gases like that currently being observed in the Arcticand strong regional to local changes associated with decadal variability in the regional circulation. Therefore, an improved understanding of drivers of regional circulation, specifically how the tropics trigger and maintain these circulation changes on interannual to decadal time scales, will allow for improved predictions of how the surface climate of Antarctica and the stability of the ice sheet due to local wind forcing of the ocean circulation will change in the future, ultimately leading to improved projections of global sea level rise.

Since Clem has been at Rutgers, in addition to research he has also attended conferences and workshops, and he has found these to be particularly helpful. I had many useful discussions with climate modelers on the various challenging steps needed to set up a climate model on a new computer.

While these events are typically short-lived, they are often very intense and they have the potential to quickly change the atmospheric circulation around Antarctica leading to extreme temperature and precipitation events. During the academic year, Clem also organized bi-weekly research meetings where meteorology faculty and graduate students presented their research.

Looking ahead to the academic year, Clem will teach a freshman undergraduate course called Academic Mentoring during the fall semester, designed to help first generation college students transition into college life.

When deciding where to apply for a postdoctoral fellowship, Clem said he chose Rutgers, and really enjoys being at Rutgers, for a variety of reasons.

I wanted to learn more about tropical meteorology and also how to perform climate model simulations so I could carry out my own sensitivity experiments to further explore these relationships.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

OARC has the goal of providing Rutgers researchers with essential computing and data handling capabilities, and students with necessary exposure and training, through centralized resources, services and training.

Even if you are a very experienced Linux user, you will want to read cluster user guide as it has slurm tips and examples.

Do not run large computational jobs on the login node. Use slurm to allocate resources on the compute node. Failure to respect the golden rule can get your account suspended. Number of jobs to submit should not exceed 5, at a time - queue is currently 10, and slurm will go to sleep if that is exceeded. Right-size your jobs: jobs may run sooner if the resources requested are smaller and your future priority is degraded if you have asked for even if not used a lot of resources lately.

For users not familiar with Linux, please familiarize yourself with Linux through tutorials and cheatsheets, or use OnDemand until you feel more comfortable with Linux.In this case we can troubleshoot and investigate why something is not working.

It is possible to specify in the slurm batch script or srun command that you wish to receive an email notification. There are two options associated with this: mail-type and mail-user.

Here is an example of how to give permission to user user1, and only to this user, to read one of my subdirectories, sharedir :. This means that by default, all directories and files are readable by group and other. The only thing stopping someone else reading your home directory is lack of x flag on the home directory.

If you add this flag to a user, now this user will also be able to read any readable files in your home directory.

So use x flag judiciously, or simply change all your permissions and user's umask in.
