It's possible to treat the symptoms of mild allergic rhinitis with over-the-counter medications, such as long-acting, non-sedating antihistamines. If possible, try to reduce exposure to the allergen that triggers the condition. See preventing allergic rhinitis for more information and advice about this.
isobar definition: 1. a line on a map connecting points having equal barometric pressure at a given reference altitude, commonly sea level, over a given period or at a given time 2. any atom that has the same atomic weight (or mass number) as another...
(Ä«'sÉ-bÃ¤r') A line drawn on a weather map connecting places having the same atmospheric pressure. The distance between isobars indicates the barometric gradient (the degree of change in atmospheric pressure) across the region shown on the map. When the lines are close together, a strong pressure gradient is indicated, creating conditions for strong winds.
