Thermal tides in the Martian atmosphere are analyzed using temperature profiles retrieved from nadir observations obtained by TIRVIM Fourier-spectrometer, part of Atmospheric Chemistry Suite onboard ExoMars Trace Gas Orbiter. The data is selected near northern summer solstice at solar longitude (LS) 75°–105° Year 35. have a full local time coverage, which enables analyses daily anomalies. obser...

The impact of the El Niño–Southern Oscillation (ENSO) on the atmospheric intraseasonal variability in the North Pacific is assessed, with emphasis on how ENSO modulates midlatitude circulation anomalies associated with the Madden–Julian oscillation (MJO) in the Tropics and the westward-traveling patterns (WTP) in high latitudes. The database for this study consists of the output of a general ci...

Abstract Global warming is changing the intensity distribution of daily precipitation, with an increased frequency heavy precipitation and reduced light/moderate in general circulation model (GCM) projections. Projected future CMIP5 GCM changes regional can be described by a combination two idealized modes: decrease mode, representing reduction at all rain rates; shift where shifts toward heavi...

[1] The mosaic approach of Liang and Wang (1997) for the general circulation model (GCM) parameterization of subgrid cloud-radiation interactions is evaluated against the validated cloud-resolving model (CRM) simulation of the Atmospheric Radiation Measurement (ARM) intensive observation period (IOP, June 22–July 17, 1997) at the Southern Great Plains (SGP) site. The CRM-generated cloud statist...

This paper introduces AMLCS-DA, a Python package designed to perform sequential Data Assimilation (DA) on Atmospheric General Circulation Models (AT-GCM). The provides implementations of well-known ensemble-based methods. default forecast step relies the AT-GCM SPEEDY. Users can define various configurations for assimilation steps, including density observational networks, background error corr...

5 Are equilibrium climate sensitivity and the associated radiative feedbacks a constant property 6 of the climate system, or do they change with forcing magnitude and base climate? Using 7 the radiative kernel technique, feedbacks and climate sensitivity are evaluated in a fully 8 coupled general circulation model (GCM) for three successive doublings of carbon dioxide 9 starting from present da...

The UVic Earth System Climate Model (version 2.8 with parameters as described in detail in (28)) includes a three-dimensional ocean general circulation model, a dynamicthermodynamic sea ice model, a simple one-layer energy-moisture balance model of the atmosphere as well as land-surface and dynamic terrestrial vegetation components at a resolution of 1.8°×3.6° with 19 vertical levels in the oce...

Current methods for climate change assessment ignore the significant differences in uncertainty model projections of two key constituents drought, precipitation, and evapotranspiration. We present here a new basis assessing future drought using simulations that addresses this limitation. The method estimates Standardized Precipitation Evapotranspiration Index (SPEI) two-stage process. first sta...

abstract the climate change was known to force local hydrology, through changes in the pattern of precipitation, temperature and the other hydrological variables. in this research, the impact of global warming on maximum and minimum temperature, precipitation and evapotranspiration (wheat, corn, tomato and sugar beet) of kashafrood basin under two climate change scenarios (a2 and b2), and the o...
