We explore the skill in seasonal forecasts of September Arctic sea-ice extent in dynamical models that are members of the Study of Environmental Arctic Change Sea Ice Outlook. We find that the multi-model ensemble only offers skill for the latest summer submission in August, and that throughout the forecasting period skill is lower than that found in hindcasts of sea-ice extent performed during earlier periods of the modern satellite record. The model-mean ensemble offers slightly higher skill, but does not beat a damped persistence forecast, helping explain why statistical models tend to outperform dynamical models. We also find that the models are equally unsuccessful at predicting each other, indicating a large divergence in model physics and/or initial conditions. Motivated by this, we perform an initial condition sensitivity experiment with four Sea Ice Outlook dynamical models. We apply a fixed perturbation to the initial conditions of minus one meter sea ice thickness anomaly, and find that while all four models have a negative sea ice area anomaly in the experiment ensembles, the magnitude of the response varies significantly. This suggests that different model physics across the Sea Ice Outlook make a significant contribution to model uncertainty and forecast skill degradation.

High impact weather events remain a considerable forecast challenge. Advances in models and data assimilation methods have led to steady improvement in forecast skill. Over the central Great Plains, mid to upper tropospheric weather disturbances often modulate severe storm development. These disturbances frequently pass over the Intermountain West region of the United States (US) during the early morning hours preceding severe weather events. This region has comparatively limited observations of the atmospheric state compared with other areas of the US, contributing toward greater potential uncertainty in forecast initial conditions. Assimilation of supplemental observations could reduce this uncertainty, and may lead to improved convective forecasts.

During spring of 2013, the Mesoscale Predictability Experiment (MPEX) used ensemble-based targeting methods to identify regions for enhanced observations expected to reduce forecast uncertainty of intense convective weather events. In particular, observations were obtained from dropsondes released from the NSF/NCAR Gulfstream-5 aircraft during the early morning hours preceding 15 severe weather events during MPEX. Retrospective data denial experiments are used to test the value of the targeted observations in reducing uncertainty in convection-permitting ensemble forecasts. Results show considerable variation in forecast impact from assimilating dropsonde observations, with an overall positive improvement, similar to prior targeted observation studies.

The seminar will provide a brief review of former observation targeting projects, examples of the method employed during MPEX, a description of the analysis and forecast system used in this study, summary performance statistics and a review of select cases to investigate case-by-case variability in dropsonde observation impact.

Statistical models using partial differential equations (PDEs) to describe dynamically evolving natural systems are appearing in the scientific literature with some regularity in recent years. Such studies seek to characterize the dynamics of temporal or spatio-temporal phenomena such as weather and climate systems, invasive species, ecological consumer-resource interactions, biological community evolution, and animal resource selection.  In the spatio-temporal setting data are often available at varying scales and the integration of a PDE may be computationally infeasible over the spatial support of interest. We present an approach to impose computationally advantageous changes of support in statistical implementations of PDE models and demonstrate its utility using a form of PDE known as "ecological diffusion." This method provides an emulator that is model specific and consistent with the inherent mathematics, and thus differs from phenomenological emulators such as those constructed using Gaussian processes.

Abstract

In this presentation, I will first briefly introduce my home lab (Laboratory for Meteorology Physics: LaMP) and describe its research domains and expertise (aerosols and cloud microphysics, observation and modeling) before dwelling more onto my own research topics: precipitation studies with x and K band radars, as well as atmospheric water vapor 3-D field restitution with GPS tomography.

This later topic will be the main object my talk, and in particular the latest preliminary results from a recent campaign for high resolution 3-D water vapor retrieval through GPS tomography as well as soil moisture monitoring with GPS reflectometry in the framework of a project dedicated to improved agriculture practice.
Indeed, with new environmental regulations in force, it becomes crucial for agricultural practices to optimize plant watering for growth as well as more reasoned use of chemical treatment products for plant fungi development suppression. Hence with the use of GNSS signal analysis, new water vapor products should enhance the impact of Precision Meteorology for Agriculture as a major tool to help agriculture decisions.

In this project, after a first step of simulations to define the optimum set of GPS receiver network geometry and analysis parameters, we implemented a demonstration network in the region of Tarascon in southern France. Using GPS tomography with the entire network proved to be able to produce reasonable water vapor field retrievals with an horizontal resolution of about 2 km and 50 m in height. Within the network, one of the stations was dedicated to reflectometry, following the work of Larsons et al. The analysis of the reflected signals, when taking into account satellite as well as field and culture configuration, showed good promise for water vapor monitoring, while actual soil moisture estimation is still a question.  

We will then discuss these results and put them in perspective for future work.

Abstract:

The rapid glaciation of tropical cumulus clouds has been an enigma and debated in the literature for over 60 years.  Possible mechanisms responsible for the rapid freezing have been postulated, but until now, direct evidence has been lacking.  Recent high-speed photography of electro-statically suspended supercooled drops in the laboratory has shown that freezing events produce small secondary ice particles, via fracturing and from spicules that eject bubbles.  

Aircraft observations from the Ice in Clouds Experiment – Tropical (ICE-T), strongly suggest that the drop-freezing secondary ice production mechanism is operating in strong, tropical cumulus updrafts.  The result is production of small ice particles settling at a few tens of cm s-1 colliding with and freezing large supercooled drops falling rapidly at a few m s-1. The large drops freeze and produce more small ice, generating a cascading process that results in rapid glaciation of water drops in the updraft.  

Results are presented from data collected using state-of-the-art cloud particle probes during 54 Learjet penetrations of strong (5 to 20 m s-1) cumulus updrafts in a temperature range from +5 to –20 C.  Repeated Learjet penetrations of updrafts containing 3 to 5 g m-3 supercooled liquid show an order of magnitude decrease in liquid mass concentration 3 to 5 min later at an elevation 1 to 1.5 km higher in the cloud.  

The aircraft observations were simulated using a one-dimensional cloud model with explicit bin microphysics.  The model was initialized with drop and ice particle size distributions observed prior to rapid glaciation.  Simulations show that the model can explain the observed rapid glaciation by the drop-freezing secondary ice production process and subsequent "riming", which results when large supercooled drops collide with ice particles.

The Southern Ocean is an important but challenging region for climate models.  In this talk, we explore the influence of low-level liquid clouds on climate model feedbacks and biases in this region.  Our findings show that thermodynamics (warming and near-surface stability), not poleward jet shifts, control Southern Ocean greenhouse climate feedbacks in the Community Earth System Model (CESM). Low-level liquid clouds are strongly affected by thermodynamics and play a central role in climate feedback strength over the Southern Ocean. These findings (Kay et al. 2014) have been affirmed in complementary studies using observations and CMIP5 (Ceppi et al. 2014, Grise and Polvani 2014). While we have found CESM a useful tool, CESM has substantial Southern Ocean biases.  One large long-standing bias is excessive absorbed shortwave radiation (ASR) over the Southern Ocean. We hypothesize that this excessive ASR bias is due in part to insufficient supercooled liquid cloud water. Our findings show that increasing supercooled liquid cloud water reduces the Southern Ocean ASR bias, but can alter global mean radiation balance sufficiently to cause runaway global cooling in some model configurations.  Indeed, “fixing” the Southern Ocean ASR bias highlights the power and challenges of global coupled climate modeling.
