Standard names: *Gust winds due to turbulence / convection*

[sol1105]

V_GUST_DYN and V_GUST_CON (gust winds due to turbulence and convection) are part of the COSMO model output, and yet lacking specific standard names.

- Term: wind_speed_of_gust_due_to_turbulence

- Description: Speed is the magnitude of velocity. Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name upward_air_velocity.) The wind speed is the magnitude of the wind velocity. A gust is a sudden brief period of high wind speed. In an observed timeseries of wind speed, the gust wind speed can be indicated by a cell_methods of maximum for the time-interval. In an atmospheric model which has a parametrised calculation of gustiness, the gust wind speed may be separately diagnosed from the wind speed. The specification of a physical process by the phrase due_to_process means that the quantity named is a single term in a list of terms, the maximum of which composes the general quantity named by omitting the phrase.

- Comment: I extended the description of the already registered standard_name "wind_speed_of_gust" (see below) by an alteration of the common "due_to_process" phrase. The problem is, that the gust winds are associated with a maximum for a time-interval. So in this case, not the sum of both terms but the maximum of both terms composes the general quantity "wind_speed_of_gust". Hence the alteration of the "due_to"-phrase.

tendency_of_air_temperature_due_to_convection Air temperature is the bulk temperature of the air, not the surface (skin) temperature. The specification of a physical process by the phrase due_to_process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. "tendency_of_X" means derivative of X with respect to time.

Thank you for these terms. I have now added these to the cfeditor (https://cfeditor.ceda.ac.uk/proposals/1). They follow the correct phrases in the description so thanks for taking the time to construct them. These look good to me. We can allow 7 days for others comment, otherwise these can be accepted.
