Spatial and Temporal Variability of Mixed Layer Depth (MLD) in Eastern Indian Ocean (EIO): 1998-2020

open access: yesJurnal Ilmiah Perikanan dan Kelautan, 2023
Mixed Layer Depth (MLD) plays an important role in various aspects of oceanography. MLD has a characteristic parameter value that is uniform with depth. MLD has an important role for local, regional, and global phenomena.

Temporal logic programs with variables [PDF]

open access: yesTheory and Practice of Logic Programming, 2016
AbstractIn this note, we consider the problem of introducing variables in temporal logic programs under the formalism of Temporal Equilibrium Logic, an extension of Answer Set Programming for dealing with linear-time modal operators. To this aim, we provide a definition of a first-order version of Temporal Equilibrium Logic that shares the syntax of ...

Selected statistical characteristics of NAO index variation according to Hurell (1864-2019)

open access: yesPrzegląd Geofizyczny, 2023
This article presents the results of several attempts to statistically characterize the short-term (year-to-year) and long-term (>10-year) variability of the NAO Hurrell index in the period 1864 – 2019 and is a complementary continuation of their ...
