Hi Everyone,<\/p>\n

Here’s another addition of Weather Trends.<\/p>\n

Part 1 – Weather Trends: Upper<\/strong> Air<\/strong>
\nIn this section, we’ll be reviewing the Upper Air Pattern. In using 500mb maps, they provide a big picture view of what happening upstairs in the atmosphere. The average 500mb plot allowed me to draw\u00a0the jet stream, which typically can be found on the 300mb or 250mb map. Here we can roughly see ridges and troughs. When I mention ridges, think of the high pressure at the surface (i.e., height lines increasing), while troughs are low pressure at the surfae (i.e., \u00a0you see the height lines dip). Troughs are typically associated with stormy weather, while ridges are the opposite, drier and stable. The 500mb anomaly maps is comparing the current analyses to climatology.\u00a0 So, the way to think of anomaly maps, its more of a signal such as where ridges and troughs are developing stronger compared to climatology. For these maps, we’ll look at the past 30 days to how the Fall Pattern has developed.<\/p>\n
