METEO 3 Lesson 6 Images

The image is a detailed surface weather map of the United States displaying various meteorological symbols and contours. The map features numerous areas of high and low-pressure systems, indicated by a blue "H" and red "L" symbol, respectively, scattered across the country. The main regions of high pressure are across the southeast, Rocky Mountains, and northern California. Solid yellow lines are drawn across the map and represent isobars, delineating areas of equal atmospheric pressure. Low pressure systems have red and blue lines with circular or triangular pips on them. The blue lines with triangular pips represent cold fronts, the red lines with circular pips represent warm fronts, and a mixed red and blue line represents a stationary front. The United States is colored in varying shades of green and brown, representing vegetation and landscape. A blue sea surrounding the map symbolizes the Atlantic and Pacific ocean regions. The NOAA logo is present at the bottom left corner of the map. In the lower part of the image, details about the map issuance in white text over a black background are visible.

The image is an illustration of a mercury barometer, displaying how atmospheric pressure is measured. The central component is a glass tube, depicted vertically, partially filled with mercury. The tube is filled with mercury at the bottom and shows air acting as a vacuum at the top. Horizontal lines on the tube serve as measurement markers. The tube is placed in a shallow circular container labeled "Mercury Reservoir," which holds additional mercury. Two downward arrows on either side of the tube are labeled "air pressure". There is also a red arrow labeled "Mercury" pointing to the mercury inside the tube. Another arrow points to the top of the column, labeled "Sea-Level Pressure 29.92 in (76 cm) (height of Mercury column)."

The center of now tropical Storm Maria made its closest approach to the US mainland earlier today. A full week after then category four Hurricane Maria became for Puerto Rico what Andrew was for parts of South Florida, what Katrina was for New Orleans, and in some ways, probably worse.

I knew the situation was dire last Wednesday morning when the timestamp on the radar image out of San Juan froze at 5:50 A.M., indicating problems with the radar. Soon, this message appeared, and now we know why. Here's what a National Weather Service Doppler radar should look like, and here's what the San Juan radar looks like now: protective dome ripped away by Maria's 100-plus mile-per-hour winds, the sensitive radar equipment inside heavily damaged. Estimated repair timeline is three to six months.

Here's what that radar saw as Maria approached Puerto Rico from the southeast, the outer bands spiraling counterclockwise across the island well before the arrival of the hurricane's core. A close-up shows that as the eye passed the island of St. Croix, the inner ring of thunderstorms evolved from circular and steady to elongated and wildly gyrating—possibly the result of interaction with St. Croix, but certainly unpredictable behavior that I wouldn't have wanted to see if I was watching from Puerto Rico.

Maria's category four winds and flooding rains devastated the island and its 3.4 million US citizens in multiple ways. In a matter of hours, about 80% of the crop value—almost $800 million in agricultural yields—was wiped out, with banana and coffee plantations hardest hit. The electric grid, including about 80% of the above-ground transmission lines, suffered catastrophic damage.

Here's a nighttime view of Puerto Rico before the hurricane hit. The brightest area on the northeast side of the island is San Juan. And here's what it looked like Monday from a satellite—much of the island completely dark, the light here primarily powered by generators. On the northwest part of the island, one of the world's most famous research telescopes at the Arecibo Observatory was damaged by falling debris. That telescope was used as the backdrop in several films, including the 1997 movie Contact.

The center of Maria spent about seven hours over Puerto Rico, the high mountains of the island weakening the hurricane to a category two. About two-thirds of the island got a foot of rain. The most measured was 37.9 inches. As the circulation moved back over water, the eye reorganized and became quite large. And the new GOES-16, high-resolution one-minute satellite imagery focusing on the center of the storm showed more bizarre behavior as small indentations and wave-like instabilities developed on the inside edge of the eye wall—hard-to-model features that illustrate why hurricane intensity forecasting is still so difficult.

As Maria heads northeast away from the East Coast into the North Atlantic, no other active tropical cyclones in the Atlantic pose a threat to the United States. Will that last into early next week? We'll have the extended forecast for you next.

The image illustrates the atmospheric layers and corresponding temperature and pressure changes with altitude. On the left side, a graph shows altitude from 0 to 50 kilometers. Two curves are depicted: a red curve for temperature (T) and a blue curve for pressure (P). The red curve shows temperature decreasing with height in the troposphere, and increasing with height in the stratosphere. The blue curve shows rapidly decreasing pressure in the troposphere with a more gradual decrease in the stratosphere. The image is divided into the troposphere at the bottom, shown with clouds and a cruising airplane at a dashed line labeled "tropopause", and the stratosphere above, with a label for the "Ozone Layer" between 20-30km. The surface, at 0km, is shades of green and brown with shades of blue in the troposphere. The ozone layer is marked by varying shades of green and above that is the stratosphere colored in dark blue. Below the graph, there are additional scales for temperature in red , ranging from -90 to 30 degrees Celsius, and pressure, from 0 to 1000mb, in blue.

The image is an illustration depicting atmospheric pressure at different elevations. It shows a cross-section of a mountain range with a gradient from dark brown at the base to light purple towards the top, representing elevation. In front of the mountains is an atmospheric pressure column labeled "KDEN," positioned at an intermediate elevation. Adjacent to KDEN is a solid vertical rectangle representing "Station Pressure," and a dashed rectangle extending to "Sea Level." Arrows and lines indicate adjustments to sea-level pressure. A label reads "Weight per unit area of fictitious column between elevation of Denver and sea level," pointing to the dashed column. The image background is a gradient of sky blue to purple, simulating an open sky.

The image is a graph illustrating the range of typical sea-level pressures in millibars (mb). It features red contour lines representing atmospheric pressure on a grid. The central focus is a blue line plotting various sea-level pressures. The right side has a range labeled from 1100 mb at the top to 900 mb at the bottom. Notable events are marked along the blue line with green and white labels. "Highest recorded sea-level pressure (1084 mb) Siberia, 1968" appears near the top left. "Lowest recorded sea-level pressure (870 mb) Typhoon Tip - 1979" is located near the bottom right. Other labels indicate pressures related to significant weather events like Hurricane Wilma in 2005 and Hurricane Andrew in 1992. The section labeled "Range of Typical Sea-level Pressures" runs vertically along the right side.

The image is an infrared satellite photograph of the United States taken on October 30, 2017, at 11:45 UTC. The photo displays various cloud formations across the country, with portions of the upper great plains and northeast experiencing significant cloud coverage. The Midwest is relatively clear in comparison. The cloud formations vary in density and texture, depicted in different shades of grey. The image includes state boundaries outlined in white for geographic reference. The northern and southern regions, including parts of Canada and Mexico, are also partially visible.

The image is a screenshot displaying maximum wind speed data organized by county for portions of Connecticut and Massachusetts. The format lists counties, specific locations, wind speed, dates, times, and data sources. Within each county, specific towns are listed with the corresponding wind speed information, date of observation, and data source. Red boxes highlight towns with particularly high wind gust reports. In Massachusetts the town of Mashpee, in Barnstable county, is highlighted with a wind gust of 93mph. Other towns such as Fairhaven in Bristol county and Duxbury in Plymouth county are also highlighted and reported windspeeds of 76 and 80mph respectively. Values are accompanied by the information source like “Trained Spotter” , “ASOS.”, or "Amateur Radio"

The image is a detailed weather map featuring isobars, station plots, and an area of low pressure with multiple types of fronts. In the top-center, a red "L" with circular isobars and a connected front indicate an area of low pressure over central North Dakota. The purple line with a mix of circular and triangular pips extending from the "L" indicates the presence of an occluded front. Near Iowa, this occlusion splits into a cold front and a stationary front. The isobars are depicted as brown lines that form concentric circles around the center of the low pressure. Small station plots scattered across the map represent weather data such as temperature, dew point, wind speed and direction, cloud cover, and pressure at various locations.

The image consists of four panels arranged in a 2x2 grid depicting a sequence of fluid dynamics in a clear double-chamber tank. Each chamber has blue liquid at different levels, separated by a vertical partition.

In the top-left panel, labeled "1", a hand is removing a barrier between the chambers. The left chamber contains more blue liquid, marked with the letter "H", indicating a higher liquid level, while the right chamber is marked with "L" for lower.

The top-right panel, labeled "2", shows the liquid from the higher chamber beginning to flow into the lower chamber, with an arrow indicating the direction of flow The chamber with less water is showing wavelike features and signs of disruption as more water enters the chamber.

The bottom-left panel, labeled "3", captures the water forming a wave as it moves to the right chamber, causing the liquid to rise.

In the bottom-right panel, labeled "4", the liquid is evenly leveled in both chambers.

The image features a simple design consisting of a red symbol on a white background to the left and text to the right. The red symbol on the left is a circle with two curve lines protruding outward in opposite directions, resembling stylized tropical storm icon. On the right, in black text, it is labeled "Tropical Storm" with a second label underneath reading "34 to 63 knots".

The video is a top-down view of the globe centered on the Arctic region and then flipping to the Antarctic region. The first half of the video shows a top-down view of the northern hemisphere where the earth appears to be rotating counter-clockwise. The view switches halfway through the video to show the southern hemisphere which appears to be rotating clockwise. It prominently displays the northern part of the Earth, showing the Arctic ice cap in white at the center. Surrounding it are parts of the northern continents, including North America, Europe, and Asia, depicted in various shades of green and brown, indicating land masses. The oceans are represented in dark blue. Overlaid on the image is a blue grid, forming a concentric pattern around the pole, possibly indicating lines of longitude and latitude.

This image is a weather map showing the Gulf Coast region of the United States, including parts of Texas, Louisiana, Mississippi, Alabama, and Florida. It features a series of concentric lines, known as isobars, indicating atmospheric pressure levels surrounding a small red hurricane symbol. The isobars are labeled with numbers indicating pressure values, such as "1000" and "1004." Red arrows on the map suggest wind direction converging towards the hurricanes center just offshore Louisiana. The map is densely populated with various station plots, represented by colored numbers and characters in different hues like red, blue, and green. These numbers represent the temperature, dew point, pressure, windspeed and direction, and cloud cover at each location.

The image is a diagram illustrating how wind blows from higher to lower pressure. It features a series of horizontal black lines representing pressure levels. At the top, the text "Lower Pressure" in red signifies the area of lower atmospheric pressure. At the bottom, "Higher Pressure" in blue indicates the area of higher pressure. A gray square in the middle has a black upward arrow pointing upward, representing a force. Next to it, a larger purple arrow labeled "Wind Vector (not in balance)" also points upward, indicating wind direction. The diagram highlights the difference in pressure and how it affects wind vectors.

The image is a diagram illustrating the interaction of pressure gradient force, Coriolis force, and friction force on wind movement. On the left, horizontal black lines depict pressure levels, with "Lower Pressure" labeled in red at the top and "Higher Pressure" in blue at the bottom. An arrow in black points from high to low pressure, representing the pressure gradient force. A red arrow represents the Coriolis force and points southeast, generally opposing the pressure gradient force. A green arrow from the opposite direction points southwest and indicates friction force and is smaller in magnitude. A purple arrow labeled "Wind Vector (Surface Wind)" shows the resultant wind direction being to the northeast. On the right, there are three vertical scales labeled Pressure Gradient, Latitude, and Friction, each with toggles for allowing Coriolis and friction effects. Below, a legend indicates arrow colors: black for pressure gradient force, red for Coriolis force, and green for friction force.

The image is a surface weather map over the southern United States, particularly focusing on the Gulf Coast region. It shows contour lines of atmospheric pressure marked with isobars, which are brown concentric circles centered over the Gulf Coast, indicating a low-pressure system. Numerous weather station symbols populate the map, displaying temperature, dew point, wind speed, and wind direction using standard meteorological notation printed in various colors such as red, green, and blue. The numbers, laid out around each station, provide specific weather data including temperatures and pressure values. Many of the isobars are labeled with their pressure contour, such as "1004" and "1000".
