Indications on the dial "Themes" and "GMT"?

[zagoranka]

Hi guys!
Hope,not too disturbing you
1). Can anyone tell me, who understood the meaning of the values ​​in each of the small circles in the theme "weather"? Probably, the upper circle shows the humidity and solar / cloud, and the others ...?)
2). "GMT" face: what shows an arrow with red tip?

Thanks in advance!)

I think, that the bottom circle is not the temperature, because, outdoor -19 C.

I think the top one is current cloud cover and maybe percentage chance of rain? One with the red line is wind direction and speed I think and bottom one is current temp and expected high temp I think? Could be wrong, anyone know for sure?
