Meteorological Applications, Volume 31, Issue 3, May/June 2024.Using conventional weather models, it is both difficult and computationally expensive to accurately simulate the urban heat island (UHI) at neighbourhood scale. We use machine learning to bias correct and downscale air temperature (T) predictions made by the Met Office operational regional forecast model to 100 m horizontal grid length over London, UK.

From microscopic interactions to the dynamics of the fireball
EPJ Web of Conferences, 2014 .We discuss recent applications of the partonic perturbative QCD based cascade model BAMPS with focus on heavy-ion phenomenology in the hard and soft momentum range.

QCD phenomenology with infrared finite SDE solutions
, 2009 Recent progress in the solution of Schwinger-Dyson equations (SDE), as well as lattice simulation of pure glue QCD, indicate that the gluon propagator and coupling constant are infrared (IR) finite. We discuss how this non-perturbative information can be

, 1999 This series of lectures consists of two parts. In the first part the foundations of perturbative and non perturbative formulation are discussed. The ambiguity in the definition of vacuum condensates is then analyzed. In the second part the symmetry patterns of the deconfining phase transition are discussed.

, 1999 There are indications of a faith transition in QCD: The strong coupling may freeze at a sufficiently low value to make PQCD relevant even in the confining regime. The properties of PQCD at low Q^2 depend on the asymptotic field configuration assumed at t=\pm\infty.

On the description of exotic hadron states within QCD sum rules
EPJ Web of Conferences, 2017 Revisiting the QCD sum-rule description of exotic hadron states, we argue that, in order to arrive at trustable analyses of, for instance, strong decay widths of multiquarks, it is inevitable to adopt the QCD sum-rule approach beyond the leading ...

Transition to Perturbative QCD
Journal of Physics: Conference Series, 2011 We review the Jefferson Lab program concerning the interplay between hadronic and underlying quark degrees of freedom in exclusive reactions. Much of the program was initially based on predictions from perturbative QCD (pQCD) concerning scaling of reaction cross sections, helicity conservation, and asymptotic behavior of form factors.

Controlling quark mass determinations non-perturbatively in three-flavour QCD
EPJ Web of Conferences, 2017 The determination of quark masses from lattice QCD simulations requires a non-perturbative renormalization procedure and subsequent scale evolution to high energies, where a conversion to the commonly used MS¯$\overline {{\rm{MS}}} $ scheme can be safely

Pomeron fan diagrams in perturbative QCD
Journal of High Energy Physics, 2018 Within QCD reggeon field theory we study the formation of two subsequent triple pomeron vertices in the process P→PP→PPP. We make use of an earlier investigation [1] of the six-reggeon amplitude in deep inelastic scattering and show that in the large-N c

A Modern View of Perturbative QCD and Application to Heavy Quarkonium Systems [PDF]
, 2014 Perturbative QCD has made significant progress over the last few decades. In the first part, we present an introductory overview of perturbative QCD as seen from a modern viewpoint.
