Summarize the following:
What most people are concerned with is precipitation, which, in meteorology (the study of weather), is any form of water that falls onto the Earth's surface. Forms of precipitation include rain, hail, snow, and sleet. Low pressure is usually associated with humid air and in some cases, precipitation. A low pressure system is an air mass that has less dense air because its air is moister and/or warmer. Surrounding air draws inward toward the low system's center as the lighter air balloons upward, often causing clouds or precipitation because that moist air cools as it rises. You see this effect when air's invisible water vapor is forced to condense into droplets when it contacts the outside of a cold glass). But droplets won't form if the glass is only slightly cool ...thus, rising low pressure air will only produce rain if it gets up where the air is cool enough to condense the water vapor into droplets too heavy to be kept aloft by the rising air. (Clouds are simply water droplets that are small enough to be kept aloft). With very low pressure systems, storms are on the way (if they aren't there already). Clouds begin to form and move across the sky -thunderhead clouds forming when moist air is thrust very high. Sometimes tornadoes form when very high pressure air collides with very warm, moist low pressure air. Watch out for one on the TV news, online, or in your local newspaper. (Other sources may include magazines and books, but they may not be current.) Newspapers are a convenient method to find a weather map as they are cheap, reliable, and can be cut apart so you can carry them with you while learning to interpret the symbols. If possible, find a map covering a smaller area these can be easier to interpret. Focusing on a larger scale may be difficult for a beginner. On the map, notice the location, lines, arrows, patterns, colors, and numbers. Every sign counts and all are different.

summary: Understand general concepts of precipitation. Understand what a low pressure system is. Study a weather map. Analyze a small portion of your weather map.

Spanish speakers usually don't say AM or PM, but rather use the words for morning (manana), afternoon (tarde), and night or evening (noche). Here's how to tell the time while indicating whether it's morning, afternoon, or evening: Es la una de la manana. It's one o'clock in the morning. Son las seis de la noche. It's six o'clock in the evening. Son las cuatro de la tarde. It's four o'clock in the afternoon. Even after you know exactly how to tell the time in Spanish, you can always improve your skills by learning a few basic phrases. Here are a few: Son las cinco mas o menos. It's about five o'clock. Es la una en punto. It's exactly one o'clock. Que hora es? What time is it?

summary: Learn to indicate whether the time is AM or PM. Learn a few additional useful phrases.

Drape your oversized blanket scarf around your shoulders, cape-style. Bring the ends of the scarf together to tie a loose knot at your chest, either centered or pulled slightly off-center. Keep the fabric loose and slouchy to achieve that chic, effortless effect. This look is perfect for dressing up office wear. Wear a yellow and gray plaid blanket scarf, knotted cape-style, with a button-down chambray shirt, tailored black pants, and some charcoal ankle boots. Wrap the scarf once around your neck, then pull the ends into a low, simple knot to keep them out of the way. This look is perfect for pairing with a professional outfit in the workplace. For example, you could throw a loosely knotted camel-colored scarf over a charcoal blazer, white button-down, black fitted dress pants, and black heels or men's dress boots. Fold or roll your scarf into a long line, then fold it in half again, lengthwise, creating a loop at one end. Place the scarf around your neck so that the loop and the 2 ends are both in front. Pull the two ends through the loop, then adjust the fabric until the knot looks relaxed and effortless. For a relaxed, professional outfit, pair a mustard yellow knit scarf, worn in the pull-through style, with a cream sweater and a pair of fitted light-wash jeans. Finish the look with some ankle-length or knee-high boots. Fold your scarf in half lengthwise, so one end is a loop. Place it around your neck so the loop and two ends are in the front. Pull one end of the scarf through the loop, then pull the bottom of the loop out slightly. Weave the second end over the top half of the loop and under the bottom to create a braided effect. Wear this style with an oversized rectangular scarf in a pretty floral pattern. Add a simple white sweater, a pair of light wash jeans, and slip-on mules.
summary: Add a loose knot to the cape style for a statement look. Tie the ends of a blanket scarf into a loose knot for a polished effect. Opt for the classic pull-through style for a professional look. Weave a simple braid to add interest to your outfit.
