Sidan är en samling av bland annat trafikverkets trafik- och väginformation. Trafikmeddelanden och olycker uppdateras var 5:e minut
och väglagsinformationen var 20:e. Under sommarmånaderna uppdateras inte väglagsinformation, halkprognos och flertalet vägväderstationer tas även ned
och visas därmed inte. Trafikinformation och senaste väglagsinformation för övriga Sverige finns under:
Sveriges trafiköversikt och viktiga trafikmeddelanden.

Lufttrycket är trycket i den sammansatta gasen som utgörs av atmosfären. Trycket
uppstår genom jordens dragningskraft (gravitationskraft) på gasmassan och minskar
med höjden över jordytan. Den sammansatta gasen som atmosfären utgörs av har därför
en minskande densitet med höjden och blir i dagligt tal "tunnare" ju högre upp man
befinner sig. Detta förhållande utnyttjas av den kommersiella flygtrafiken genom
att luftmotståndet minskar ju högre upp flygplanet flyger. Samtidigt minskar mängden
syre varför man för vanliga jetmotorer funnit att en höjd på cirka 10 000 m utgör
den optimala höjden med avseende på luftmotstånd och nödvändigt syreinnehåll för
att få tillräckligt dragkraft från motorerna.
För mätningar av aktuellt lufttryck används en barometer. SI-enheten för lufttryck
är hPa men enheterna millibar (tusendels bar) och mmHg (mm kvicksilverpelare) förekommer
även i olika omfattningar.
