I am exporting in ArcGIS a raster by doing Data > Export data. But in the Export Raster Data window, I don't have the option for choosing the file format.
Am I missing something? Perhaps must the Coordinate reference system of the raster be a projected one?
The problem is not in the licensing or action of the export function. It is a matter of understanding how the Export Raster function works.
Based on your description, you are trying to select some number of cells from the raster, then do as you would a standard feature class in ArcMap and Export using a right click on the Layer Name.
If you did this on a Featur eclass with features selected, the window that comes up would look like this:
By default, the "Selected Features" option is used when there are features selected in the layer.
Rasters work somewhat differently when you export them. Here is the export window on a Raster, showing the Selected Graphics option grayed out, as you mentioned.
This Help document explains about Exporting a raster in ArcMap. In it, you see this section about Selected Graphics:
The Selected Graphics (Clipping) will clip and export the raster dataset based on the selected graphics in the display; this option will retain the data inside the graphic. Alternatively, you can check the Clip Inside option to remove the data within the graphic and keep the rest of the data.
What this is referring to, is not about selecting specific records from the attribute table that you want to export, but rather selecting a graphic in the Data Frame, that you want to clip your raster to, like the polygon below:
You can create Graphics with the Draw toolbar (more information here).
Right clicking to export the raster with the graphic selected, gives you the following option enabled in the window:
If you do want to Export Records from your Raster Attribute Table, you need to follow the procedure from this Help Document: Exporting a raster attribute table
You should not export the wind map as RGB GeoTIFF but rather as Floating point GeoTIFF.

The dialog for Data::Export Data contains the format:
It's been that way since at least version 9. This screen shot is from v10.1 and 10.2 is very similar (just a different drop down style).
