Record 1 2023-03-07

English

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
DEF

A deep convective system which is considerably larger than an individual thunderstorm ...

CONT

A particular type of MCS [mesoscale convective system], an MCC is a large, circular, long-lived cluster of showers and thunderstorms identified by satellite. It often emerges out of other storm types during the late-night and early-morning hours. MCCs can cover an entire state.

OBS

The area with a temperature below −52 °C must exceed 50 000 km², and there must be a continuous area, exceeding 100 000 km², below −32 °C. This larger area must be elongated, with an eccentricity (ratio of minor axis to major axis) of 0.7 or more. These criteria must be satisfied for a period of more than 6 hours for the classification to apply.

OBS

... it is often marked by an extensive middle-to-upper tropospheric stratiform-anvil cloud of several hundred kilometres in breadth.

Key term(s)
  • meso-scale convective complex

French

Domaine(s)
  • Phénomènes météorologiques, climatiques et atmosphériques
DEF

Système convectif de grande extension verticale et d'étendue considérablement plus grande qu'une simple cellule orageuse [...]

CONT

Plus spécifiquement, les complexes convectifs de méso-échelle (CCM), un type de SCM [système convectif de méso-échelle] large et persistant, sont associés à des précipitations intenses pouvant causer des inondations, le tout accompagné de vents forts.

OBS

[...] il est souvent associé à un nuage stratiforme en forme d'enclume des niveaux moyens à supérieurs de la troposphère qui peut s'étendre horizontalement sur plusieurs centaines de kilomètres.

Spanish

Campo(s) temático(s)
  • Fenómenos meteorológicos, climáticos y atmosféricos
DEF

Sistema convectivo profundo apreciablemente mayor que una célula tormentosa simple [...]

OBS

[...] se caracteriza a menudo por la presencia de una nube estratiforme en forma de yunque que va de los niveles medios a los superiores de la troposfera y que puede tener una extensión horizontal de varios centenares de kilómetros.

Record 2 2015-02-26

English

Subject field(s)
  • Meteorological Forecasting, Data Measurement and Analysis
  • Atmospheric Physics
DEF

Size scale referring to weather systems smaller than synoptic-scale systems but larger than storm-scales systems.

CONT

Mesoscale [refers to] dimensions of an atmospheric layer which ranges from a few kilometres to some tens of kilometres horizontally and, vertically, from the ground to the top of the friction layer.

OBS

mesoscale. ... Horizontal dimensions generally range from around 50 miles to several hundred miles. Squall lines, MCCs [Mesoscale Convective Complexes], and MCSs [Mesoscale Convective Systems] are examples of mesoscale weather systems.

Key term(s)
  • meso scale
  • sub-synoptic scale

French

Domaine(s)
  • Prévisions météorologiques et mesure et analyse des données
  • Physique de l'atmosphère
CONT

[Les termes] «méso-échelle» et «échelle moyenne» [se rapportent aux] dimensions d'une couche atmosphérique s'étendant horizontalement de quelques kilomètres à quelques dizaines de kilomètres et, verticalement, du sol au sommet de la couche de frottement.

CONT

Pour l'étude de certains phénomènes locaux, tels la structure des orages, les effets du vent sur les constructions, etc., les échelles d'espace et de temps doivent être beaucoup plus fines, on parle alors d'échelle moyenne ou aérologique.

Spanish

Campo(s) temático(s)
  • Previsiones meteorológicas, medición y análisis de datos
  • Física de la atmósfera
CONT

mesoescala [se refiere a las] dimensiones de una capa atmosférica que se extiende horizontalmente de unos pocos kilómetros a varias decenas de kilómetros y, verticalmente, del suelo a la cima de la capa de fricción.

Record 3 2004-02-17

English

Subject field(s)
  • Meteorological Forecasting, Data Measurement and Analysis
DEF

Analysis of mesoscale phenomena, such as fronts and cloud clusters, with scales ranging from a few to some tens of kilometres.

CONT

The analysis seeks to define mesoscale features of the observed temperature, pressure, moisture, and wind fields that can be related to important local and regional circulations that in turn may have a significant impact on local and regional weather systems. The mesoanalysis differs from the more conventional synoptic-scale representation of the wind and pressure features in that smaller-scale features inherent in the wind, pressure, and moisture fields are retained in the analysis.

Key term(s)
  • meso-analysis
  • meso analysis

French

Domaine(s)
  • Prévisions météorologiques et mesure et analyse des données
DEF

Analyse de phénomènes de méso-échelle, tels que fronts et amas de nuages, à des échelles se situant entre quelques kilomètres et quelques dizaines de kilomètres.

Spanish

Campo(s) temático(s)
  • Previsiones meteorológicas, medición y análisis de datos
DEF

Análisis de los fenómenos de mesoescala, tales como los frentes y las aglomeraciones de nubes convectivas, con escalas que van de unos kilómetros a unas decenas de kilómetros.

Key term(s)

French

Domaine(s)
  • Physique de l'atmosphère
DEF

Perturbation à méso-échelle des champs de pression et de flux.

Key term(s)

CONT

Important mesoscale features in the wind, temperature, moisture, and pressure fields are illustrated on the mesochart by means of contours and/or colored (or black-and-white) shading.

Key term(s)
  • meso-chart

French

Domaine(s)
  • Prévisions météorologiques et mesure et analyse des données
DEF
