The Astronomical vs. Meteorological Seasons

The Astronomical vs. Meteorological Seasons If someone asked you when each of the seasons occurs, how would you respond?  Your answer may depend on whether you think of the seasons  in a more traditional, or  a more weather-related way. Astronomical Seasons Change at the Equinoxes and Solstices The astronomical seasons are the ones most of us are familiar with because  their  start dates are  listed on our calendars. Theyre called astronomical because, like our calendar, the  dates of their occurrence are based on the position of Earth in relation to the sun. In the Northern Hemisphere: Astronomical winter is a result of Earths north pole being tilted its farthest away from the sun,  and the suns light aiming directly at southern latitudes. It begins on December 21-22.  Astronomical spring is a result of Earths north pole tilt moving from its maximum lean  away from the sun to one equidistant from the sun,  and of the suns light aiming directly at the equator. It begins on March 21-22.  Astronomical summer is a result of Earth being tilted its farthest towards  the sun, and the suns light aiming directly at north latitudes. It begins on June 20-21.Astronomical fall is a result of Earths tilt moving from its maximum lean  towards the sun to one  equidistant from the sun,  and of the suns light  aiming directly at the equator. It begins on September 21-22. Meteorological Seasons Change Every 3 Months Another  way to define  the seasons is by grouping the twelve calendar months into four 3-month periods based on  similar temperatures. In the Northern Hemisphere: Meteorological winter  begins on December 1. It includes the months of  December, January, and February (DJF)Meteorological spring  begins on March 1 and includes the months of  March, April, and May  (MAM).Meteorological summer  begins on June 1. It includes the months of  June, July, and August (JJA).Meteorological fall  begins on September 1 and includes the months of  September, October, and November (SON). Meteorologists didnt implement this classification just for the heck of it. Rather, they prefer to deal with data from whole rather than fractions of months, and align calendar dates more closely with the temperatures felt during that period, the scheme (which has been around since the early- to mid-1900s) allows weather scientists  to more easily compare weather patterns from one season to another something the astronomical convention makes cumbersome due to seasonal lag (the delay in seasonal temperatures settling in). Which Set of Seasons Wins Out? The astronomical seasons are the more traditional way of defining our four seasons. Although folks may not be used to the meteorological way, in a lot of ways its the more natural scheme for how we live our lives today. Gone are the days when we pore over the happenings of the celestial heavens and organize our lives accordingly. But organizing our lives around months and similar stretches of temperatures is more true to our modern reality.

Dorothy Height Quotations

Dorothy Height Quotations Dorothy Height, a key figure in the American civil rights movement, worked for many years for the YWCA, and also headed the National Council of Negro Women for more than 50 years. Selected Dorothy Height Quotations If you worry about who is going to get credit, you dont get much work done. Greatness is not measured by what a man or woman accomplishes, but by the opposition, he or she has overcome to reach his goals. I was inspired by Mary McLeod Bethune, not only to be concerned but to use whatever talent I had to be of some service in the community. As I reflect on the hope and challenges facing women in the 21st century, I am also reminded of the protracted struggles of African-American women who joined together as SISTERS in 1935 in response to Mrs. Bethunes call. It was an opportunity to deal creatively with the fact that Black women stood outside of Americas mainstream of opportunity, influence, and power. I want to be remembered as someone who used herself and anything she could touch to work for justice and freedom.... I want to be remembered as one who tried. A Negro woman has the same kind of problems as other women, but she cant take the same things for granted. As more women enter public life, I see developing a more humane society. The growth and development of children no longer will depend solely upon the status of their parents. Once again, the community as the extended family will rekindle its caring and nurturing. Though children cannot vote, their interests will be placed high on the political agenda. For they are indeed the future. 1989, about using the term black or African-American: As we move ahead into the 21st century and look at a unified way of fully identifying with our heritage, our present, and our future, our use of African-American is not a matter of putting down one to pick up the other. It is a recognition that weve always been African and American, but we are now going to address ourselves in those terms and make a unified effort to identify with our African brothers and sisters and with our own heritage. African-American has the potential of helping us to rally. But unless we identify with the full meaning, the term wont make a difference. It becomes merely a label. When we started using the term Black, it was more than a color. It came at a time when our young people in marches and sit-ins made the cry Black Power. It represented the Black experience in the United States and the Black experience of those throughout the world who were oppressed. We are at a different point now. The struggle continues, but its more subtle. Therefore, we need, in the strongest ways we can, to show our unity as a people and not just as a people of color. It was not easy for those of us who had become symbols of the struggle for equality to see our children raising their fists in defiant contradiction of all we had fought for. No one will do for you what you need to do for yourself. We cannot afford to be separate. We have to see that all of us are in the same boat. But were all in the same boat now, and weve got to learn to work together. We are not a problem people; we are a people with problems. We have historic strengths; we have survived because of family. We have to improve life, not just for those who have the most skills and those who know how to manipulate the system. But also for and with those who often have so much to give but never get the opportunity. Without community service, we would not have a strong quality of life. Its important to the person who serves as well as the recipient. Its the way in which we ourselves grow and develop. Weve got to work to save our children and do it with full respect for the fact that if we do not, no one else is going to do it. There is no contradiction between effective law enforcement and respect for civil and human rights. Dr. King did not stir us to move for our civil rights to have them taken away in these kinds of fashions. The Black family of the future will foster our liberation, enhance our self-esteem, and shape our ideas and goals. I believe we hold in our hands the power once again to shape not only our own but the nations future a future that is based on developing an agenda that radically challenges limitations in our economic development, educational achievement, and political empowerment. Undoubtedly, African-Americans will have an integral role to play, although our path ahead will continue to be complex and difficult. As we move forward, let us also look back. So long as we remember those who died for our right to vote and those like John H. Johnson who built empires where there were none, we will walk into the future with unity and strength.
