• Hello! I wanted to show you a situation I noticed in the United States in Perry, Florida. With atmospheric pressure at 1017 hPa, CAPE at 1100 + -. I saw lightning happening in real time and went to investigate the curves of sounding diagrams. I noticed that thunderstorms are forecast in the surrounding hours but the red temperature line was below the humid adiabatical although the blue line is very close to the red line. Now my question is: If the red temperature line is above the humid adiabatic, shouldn't it inhibit vertical development? And not form storms? Shouldn't the warmer surrounding air keep the adiabatic bubble from rising? I leave images taken. Give me the best explanation with this example. Thank you

  • So I've been interested in meteorology and weather for some time now and now I'm Iearning about weather stations and data they're reporting. As most of you here probably know, there are two types of weather reports: METAR and SYNOP. The thing is, METAR reports have often higher temperatures than SYNOP. Official weather data seems always to rely on SYNOP readings, even though from what I've read METAR is considered to be the most accurate. Why is it like that ? Which data is more reliable ?

    Weather observations from METAR and SYNOP have the same accuracy.
    METARs are half-hourly or hourly observations.
    SYNOPs are observations made in a 3-hours basis (00 UTC, 03 UTC, 06 UTC etc).

    Example: SYNOP at 12 UTC shows temperature 20C.
    Next SYNOP at 15 UTC shows 22C.

    METARS (for the same time period) may show:
    METAR 12 UTC, 20C
    METAR 13 UTC, 23C
    METAR 14 UTC, 24C
    METAR 15 UTC, 22C.
