Summary: The influence of methane on the circulation of Titan is investigated using a simplified moist convection parameterization scheme. The results show that the reference relative humidity has a significant impact on convective instability and precipitation, while the relaxation timescale of convection has minor effects. The behavior of convection varies with the relative humidity, with infrequent and intense events at low relative humidity and near-continuous precipitation at high relative humidity during summer. Intermediate relative humidity values result in frequent events of moderate intensity.

Summary: This article investigates the impact of temporal variations in flowing river networks on species persistence and spread. The study finds that network dynamics have a detrimental effect on species spread and persistence, particularly in dry climates and settings with pronounced spatial heterogeneity of network connectivity.

Summary: Results from an experimental campaign on the aerodynamics of 3D-printed analogues of ice particles show that commonly used parametrisations of ice particle fall speeds become less accurate at high Reynolds numbers. A new fall speed parametrisation is proposed to predict drag coefficients with high accuracy at high Reynolds numbers.

Summary: This paper investigates the application of cryogenic minimum quantity lubrication (CMQL) in the machining of titanium thin-wall components. Comparative experiments show that CMQL machining can significantly lower the cutting loads and deformation values of thin-wall parts and enhance the wear resistance of the cutting tool and surface quality. The experimental outcomes demonstrate the feasibility of CMQL in improving the machinability of thin-wall components made from difficult-to-cut material.

Summary: Hip arthroplasty is a common procedure, but some patients experience persistent pain after the surgery. The complications depend on various factors such as post-operative delay, material type, patient characteristics, and surgical approach. Radiographs, CT, and MRI are commonly used imaging modalities for diagnosis, but there is still no consensus on the optimal imaging workup for complications.

Summary: In this paper, a high-fidelity finite element model was established to study the buckling behaviors of thin-walled cylindrical shell under localized axial compression load. The feasibility and accuracy of the model were validated through comparison with experimental results. Factors such as material yield strength and initial geometric imperfections were found to play dominant roles in the buckling behaviors of cylindrical shells under localized axial compression loads, providing guidance for design and application in engineering.

Summary: A methodology combining multiple model projections and a simplified shoreline evolution model is used to predict coastal changes in a highly anthropized area along the Mediterranean coast of Spain. By analyzing time series of shoreline evolution, both long-term and short-term processes are revealed, providing insights into different physical contributions to shoreline change and extreme retreat scenarios.

Summary: This study presents a unified theory that includes all existing covariance inflation methods, and proposes adaptive inflation methods to estimate inflation functions in real time from observations. Through maximum likelihood estimation, it is demonstrated that this method is effective and can outperform well-tuned CI methods.

Summary: The effect of wetting time on localized corrosion of AA5083-H111 aluminum alloy in a dynamic seawater/air interface zone was investigated. Longer wetting time resulted in a more serious localized corrosion degree and thus led to an uneven and incomplete corrosion product film. This was attributed to the presence of a thin electrolyte layer upon the alloy, restricting the repassivation of the corrosion pits.

Summary: This paper provides a quantitative assessment of large-scale features in a perturbed parameter ensemble of Met Office Unified Model HadGEM-GC3.05 in coupled global historical and future simulations. The evaluation process of the 20 PPE members showed diverse atmosphere and ocean model behaviors which contribute to a more complete picture of plausible impacts. The final product, a combined projection system of 15 PPE members and 13 CMIP5 models, offers a wider range of outcomes that can provide users with valuable insights.

Summary: The important role of carbon monoxide (CO) in the Martian carbon cycle has led to numerous measurements from ground and space, with daytime measurements being more common than night-time observations. This study demonstrates the feasibility of using PFS night-time observations to measure Martian CO abundance, highlighting the importance of high surface temperatures and high thermal contrast for successful detection. Night-time PFS observations provide a stronger constraint on near-surface CO abundance in the 0-10 km altitude region compared to daytime observations, especially in the Southern Hemisphere during spring and summer.

Summary: In this paper, a nonlinear theory of self-oscillatory solidification mode during directional crystallization in the presence of a quasi-equilibrium two-phase region of constitutional supercooling is developed. The study demonstrates that this mode can be formed due to the oscillatory instability at certain values of physical and operating parameters of the system, based on the linear stability theory. The development of oscillatory instability is explained using a new frontal model of crystallization with a two-phase region, where a discontinuity surface replaces the real two-phase region.

Summary: Antarctic sea ice in CESM2 is thinner and less extensive compared to CESM1, but the annual cycle of ice growth and melt is more vigorous. The new mushy layer thermodynamics formulation in CESM2 accounts for greater frazil ice formation in coastal polynyas and more snow-to-ice conversion near the edge of the ice pack.

Summary: This paper introduces an implicit ensemble TLM (IETLM) to predict the difference between perturbed and unperturbed nonlinear forecasts. The accuracy of the IETLM is confirmed in the linear regime and a diagonally robust (DR) IETLM is developed for ensemble perturbations in the nonlinear regime. The performance of the DR IETLM is found to match that of the traditional TLM over a wide range of non-linearity.

Summary: Data assimilation (DA) is the process of merging information from prediction models with observations to estimate the state of a physical system. In the context of ionospheric physics-based models, this study focuses on understanding how a DA algorithm responds to estimating an external parameter driving the model's interpretation of solar ionizing radiation. The results demonstrate the impact of solar forcing and recombination on the estimation process in a linear and Gaussian framework.

Summary: Comparisons of TEC variability among two SAMI3 model runs and JPL/GIM show that there is a non-zero large-scale base correlation in all three datasets for the year 2014 with high solar activity. The SAMI3 runs generally exhibit higher correlations than JPL/GIM, and the correlation values strongly correlate with monthly F10.7 standard deviations.
