Freezing Rain Definition

Freezing Rain Definition While beautiful to look at, freezing rain is one of the most hazardous types of winter precipitation. Accumulations of just several tenths of an inch of freezing rain may not sound significant, but are more than enough to break tree limbs, down power lines (and cause power outages), and coat and cause slick roadways. The Midwest often gets devastating storms of this nature. Rain that Freezes On Contact Freezing rain is a bit of a contradiction. The freezing part of its name implies frozen (solid) precipitation, but the rain implies its a liquid. So, which is it? Well, its kind of both. Freezing rain happens when precipitation falls as liquid raindrops, then freezes as it hits individual objects on the ground whose temperatures are below 32 degrees Fahrenheit. The ice that results is called glaze ice because it covers the objects in a smooth coating. This happens in winter whenever temperatures at ground-level are below freezing but the layer of air overhead is warm at mid- and high levels of the atmosphere. So it is the temperature of objects at the earths surface, not the rain itself, that determines if the precipitation will freeze. Its important to note that freezing rain is in liquid form until it strikes a cold surface. Oftentimes, the water droplets are supercooled (their temperature is below freezing, yet they remain liquid) and freeze on contact. How Fast Freezing Rain Freezes While we say that freezing rain freezes on impact when it strikes a surface, in reality, it takes a little time for the water to turn to ice. (How long depends on the temperature of the water drop, the temperature of the object the drop strikes, and the size of the drop. The quickest drops to freeze will be small, supercooled drops that hit objects whose temperatures are well below 32 degrees.) Because freezing rain doesnt necessarily freeze right away, icicles and dripping icicles will sometimes develop.   Freezing Rain vs. Sleet Freezing rain and sleet are similar in a lot of ways. They both start out high in the atmosphere as snow, then melt as they fall into a warm (above freezing) layer of air. But while the partially melted snowflakes that eventually turn into sleet will fall through a brief warm layer, then re-enter a deep enough cold layer to turn back into ice (sleet), in a freezing rain setup, the melted snowflakes dont have enough time to freeze (into sleet) before reaching the ground since the layer of cold air is too thin.  Ã‚   Sleet not only differs from freezing rain in how it forms, but what it looks like. Whereas sleet appears as tiny clear ice pellets that bounce when they hit the ground, freezing rain coats the surfaces it strikes with a layer of smooth ice.   Why doesnt it just snow? In order to get snow, temperatures throughout the atmosphere would need to remain below-freezing with no warm layer to be found. Remember, if you want to know the type of precipitation youll get at the surface in wintertime, youll want to look at what the temperatures are (and how theyre changing) from high up in the atmosphere all the way down to the surface. Heres the bottom line: Snow forms if the entire layer of air aloft and near the ground is sub-freezing.Sleet forms if the layer of sub-freezing air is fairly deep (approx. 3,000 to 4,000 feet thick).Freezing rain forms if the sub-freezing layer is very shallow, with cold temperatures at the surface only.Rain forms if the cold layer is too shallow.

Biography of Alice Walker, Pulitzer Prize Winning Writer

Biography of Alice Walker, Pulitzer Prize Winning Writer Alice Walker (born February 9, 1944) is a writer and activist, perhaps best known as the author of The Color Purple and more than 20 other books and poetry collections.  She is also known for  recovering the work of Zora Neale Hurston and for her work against female circumcision.  She won the Pulitzer Prize in 1983 and the National Book Award in 1984. Fast Facts: Alice Walker Known For: Writer, feminist, and activistBorn: February 9, 1944 in Eatonton, GeorgiaParents: Minnie Tallulah Grant and Willie Lee WalkerEducation: East Putnam Consolidated, Butler-Baker High School in Eatonton, Spelman College, and Sarah Lawrence CollegePublished Works: The Color Purple, The Temple of My Familiar, Possessing the Secret of JoySpouse: Melvyn R. Leventhal (m. 1967–1976)Children: Rebecca Leventhal (b. November 1969) Early Life Alice Walker was born on February 9, 1944, in Eatonton, Georgia, the last of eight children born to Minnie Tallulah Grant and Willie Lee Walker. Her parents were sharecroppers who worked on a large cotton farm during the days of Jim Crow. Recognizing Alices abilities at a very young age, her mother got the 4-year old into first grade at East Putnam Consolidated, where she quickly became a star pupil. In 1952, a childhood accident blinded her in one eye. Medical conditions in the Jim Crow south meant she did not get proper medical treatment until six years later when she visited her brother in Boston, Massachusetts. Nevertheless, she went on to become valedictorian of her class at Butler-Baker High School. At 17, Walker received a scholarship to attend Spelman College in Atlanta, where she became interested in Russian literature and the burgeoning Civil Rights movement. In 1963, she was offered a scholarship to Sarah Lawrence College, and, after her activist mentor Howard Zinn was fired from Spelman, Walker transferred to Sarah Lawrence. There, she studied poetry with Muriel Rukeyser (1913–1980), who would help her get her first collection of poems, Once, published in 1968. In her senior year, Walker studied in East Africa as an exchange student; she graduated in 1965. Professional Life After college, Alice Walker worked briefly for the New York City Department of Welfare and then returned to the south, moving to Jackson, Mississippi. In Jackson, she volunteered in voter registration drives and worked for the Legal Defense Fund of the NAACP. She met fellow civil rights worker Melvyn R. Leventhal on March 17, 1967, and they married in New York and moved back to Jackson, where they were the first legally married biracial couple in the city. They had one daughter, Rebecca, born November 17, 1969, but the marriage ended in divorce in 1976. Alice Walker started her professional writing career as a writer-in-residence first at Jackson State University (1968–1969) and then at Tougaloo College (1970–1971). Her first novel,  a three-generation saga of sharecroppers called The Third Life of Grange Copeland, was published in 1970. In 1972, she taught a course in Black Womens Writers at the University of Massachusetts in Boston. She continued steadily writing throughout this period. Early Writing By the mid-1970s, Walker turned to her inspirations from the Harlem Renaissance period of the early 20th century. In 1974, Walker wrote a biography of poet Langston Hughes (1902–1967), and the following year she published a description of her research with Charlotte Hunt, In Search of Zora Neale Hurston, in Ms.  magazine. Walker is credited with reviving interest in the writer/anthropologist (1891–1960). Her novel Meridian came out in 1976, and the subject was the civil rights movement in the south. Her next novel, The Color Purple, changed her life. Alice Walkers poems, novels, and short stories frankly deal with rape, violence, isolation, troubled relationships, bi-sexuality, multi-generational perspectives, sexism, and racism: all of the things which she knew from her personal experiences. Always, and more as she grew as a writer, Alice Walker has been unafraid to be controversial. The Color Purple When The Color Purple came out in 1982, Walker became known to an even wider audience. Her Pulitzer Prize and the movie by Steven Spielberg brought both fame and controversy. She was widely criticized for negative portrayals of men in The Color Purple, though many critics admitted that the movie presented more simplistic negative pictures than the books more nuanced portrayals. In two books- The Temple of My Familiar (1989) and Possessing the Secret of Joy (1992)- Walker took on the issue of female circumcision in Africa, which brought further controversy: was Walker a cultural imperialist to criticize a different culture? Legacy Alice Walkers works are known for their portrayals of the African-American womans life. She depicts vividly the sexism, racism, and poverty that make that life often a struggle. But she also portrays as part of that life, the strengths of family, community, self-worth, and spirituality. Many of her novels depict women in other periods of history than our own. Just as with non-fiction womens history writing, such portrayals give a sense of the differences and similarities of womens condition today and in that other time. Alice Walker continues not only to write but to be active in environmental, feminist/womanist causes, and issues of economic justice. Her latest novel, Now is the Time to Open Your Heart, was published in 2004; since that time her published work has been poetry. In 2018, she published a collection of poems titled Taking the Arrow Out of the Heart. Sources Alice Walker: By the Book. The New York Times, December 13, 2018.  Howard, Lillie P (ed.).
